 Jean Gagnon & Marguerite Cochon

Merchants, Landowners and Pioneers of New France

Jean Gagnon, son of Pierre Gagnon and Renée (or Magdeleine) Roger, was born in the village of La Gagnonnière, located between Tourouvre and Ventrouze in the old French province of Perche. He was baptized “Jehan Gaignon” on August 13, 1610, in the parish of Saint-Aubin in Tourouvre. His godparents were Jehan Creste and Jehanne Gaignon. His paternal grandparents were Barnabé Gagnon and Françoise Creste, while his maternal grandparents were Gervais Roger and Marion Aubert. Jean’s family name appeared in a variety of phonetic ways on documents, including Gaignon, Gasgnon, and Gangnon.

The Gagnon family owned a farm and an inn in La Gagnonnière. Jean had six siblings: Noël, Louis, Mathurine, Marguerite, Mathurin, and Pierre. The latter three would also become pioneers in New France.

Jean’s departure for Canada formed part of a much larger migration from Perche that played an important role in the early settlement of New France.

Arrival in New France

Jean sailed to New France with his brothers Mathurin and Pierre sometime between 1635 and 1640. The three brothers were merchants who operated a store on rue Saint-Pierre in Québec’s lower town. The property measured approximately 24 feet wide by 60 feet deep. Joseph Massé Gravel dit Brindelière was a co-proprietor; he would later marry Marguerite Tavernier, the Gagnon brothers’ niece (daughter of Marguerite Gagnon and Éloi Tavernier). 

By 1640, Jean was established on a tract of land on the Beaupré coast at Château-Richer. The property measured seven arpents of frontage on the St. Lawrence River by 126 arpents in depth; formal title to the concession was issued on July 20, 1652. Between 1640 and 1652, Jean bought and sold land in Château-Richer but held onto his original concession.

In 1642, Mathurin returned to France to attend to family and business affairs. The following year, he returned to Canada with his daughter Marie Marthe. Around the same period, his sister Marguerite Gagnon and her husband, Éloi Tavernier, also settled in New France with their daughters Marguerite and Marie. Their mother, Renée (or Magdeleine) Roger, likewise emigrated to Canada, although sources differ as to the exact year of her arrival.

Marguerite Cochon (or Cauchon), daughter of Jean Cauchon and Marguerite Cointel (or Cointerel), was born around 1620 in the parish of Saint-Jacques in Dieppe, Normandy, France.

Dieppe sits in northern France, in the Seine-Maritime department. Today, the city has approximately 30,000 inhabitants, known as Dieppois. As a major port, it distinguished itself in the 16th century for its contribution to the French school of cartography.   

Marguerite grew up in Dieppe with four brothers: Guillaume, born in January 1624; Jean, born around 1627; Pierre, baptized on July 17, 1631; and Nicolas, born and baptized on January 9, 1633. Their mother, Marguerite Cointel, died that same day at about 40 years of age, and the infant Nicolas died three days later. Their father, Jean Cauchon, remarried Jeanne Abraham in early April 1633. Marguerite subsequently gained at least three half-siblings: Françoise, baptized in Dieppe on December 7, 1633; Jacques, baptized there on February 6, 1635; and an unnamed child born and buried in Québec on March 27, 1642. The family appears to have migrated to New France during the latter half of the 1630s, and Marguerite was established there by 1640, when she married Jean Gagnon.

On Canadian documents, the family name was spelled both Cochon and Cauchon. Marguerite signed her name Cochon.

Marriage and Children

Jean “Gangnon” and Marguerite “Cochon” were married on July 29, 1640, in Beaupré. [The record is preserved in the Québec register now catalogued under Notre-Dame-de-Québec.] He was 29 years old; she was about 20. The witnesses were Pierre Legardeur d’Arpentigny; Noël Juchereau, sieur des Châtelets; and Jean Bourdon. [The marriage record incorrectly describes both of Jean’s parents as deceased; his mother was still living.]

Jean and Marguerite settled on the côte de Beaupré, where they had at least eight children:

1. Jeanne (1641–1699)

2. Renée (1643–bef. 1702)

3. Marguerite (1645–bef. 1705)   

4. Jean (1648–1687)

5. Étienne (1650–bef. 1666)

6. Germain (1653–1708)

7. Raphaël (1656–1687)

8. Marie (1659–1722)

Business and Property in Québec

On August 14, 1651, the three Gagnon brothers received a land concession from Louis d'Ailleboust, which was ratified by Jean de Lauson on December 1, 1652. The concession involved three-quarters of a site located on rue Saint-Pierre, in the lower town of Québec, measuring four toises wide by ten toises long, on which there was a main building consisting of three rooms with chimneys, three bedrooms, and three attics. [The toise was an old measure of length equal to six feet.]

On October 6, 1653, Jean was involved in two notarial transactions recorded by notary Guillaume Audouart dit Saint-Germain:

• Six-month lease agreement for one half of the cellar of a shop and house located on the port of Québec by Pierre, Jean, and Mathurin Gagnon, brothers, and Massé Gravel dit Brindelière, to merchant Jean Garos of La Rochelle, for 90 livres.

• Contract for the carpentry and flooring of the same house located in the port of Québec by Michel Bourdet and Pierre Biron, carpenters, for Jean, Pierre and Mathurin Gagnon, brothers, and Massé Gravel dit Brindelière, for 135 livres.

Before the same notary, four years later on September 9, 1657, Jean recognized that he owed Robert Tauvé the sum of 152 livres, 9 sols, 6 deniers, for a cash loan. Jean incurred the debt to finance the transportation from France of an engagé, or hired servant, who was to work for him in New France.  

Family and Community Life

On February 2, 1660, Jean and Marguerite, as well as their children Renée, Jean, Jeanne, and Marguerite, received the sacrament of confirmation from François de Montmorency-Laval, “Monsignor the Illustrious and Most Reverend Bishop of Petrée, Vicar Apostolic in the whole of New France,” in Château-Richer, alongside 169 other people.

The following month, on March 7, 1660, notary Claude Auber penned an agreement between Jean and his son-in-law Jean Chapeleau, the husband of Jeanne Gagnon. The pair formally settled their outstanding mutual accounts, which included money, work performed, provisions, and apparently matters involving livestock. After the accounts were reconciled, Jean owed his son-in-law 160 livres.

The Gagnon Family in the Census

In 1666, Jean and Marguerite were recorded in the census of New France living on the côte de Beaupré (in Château-Richer) with their five children and one domestic servant, Étienne Mesny.

The following year, another census was taken. Jean and Marguerite were still living in Beaupré with their four children and a different domestic servant, Noël Viard. They owned 8 head of cattle and 30 arpents of cleared or cultivated land.

Final Property Transactions

Jean appeared in two last notarial documents before his death.

On February 21, 1667, Jean and his brother Pierre purchased a plot of land located on the côte and seigneurie of Beaupré from Nicolas Quentin [Cantin] and Madeleine Roulloy [Roulois] for 1,800 livres. The land measured four arpents of frontage facing the St. Lawrence River, bordering Jean’s own land and that of Martin Guérard. It was subject to a seigneurial rente of 20 sols for each arpent of frontage, plus two live capons for the entire property, due annually on the feast day of Saint Martin, November 11. On this document, we see Jean’s signature for the first time, where previously he had only left his mark.  

On October 9, 1668, Jean sold his interest in the Québec property to bourgeois Pierre Pellerin de St-Amand and Louise de Monceaux for 300 livres. Located on “the street running from the Place d’Armes to the Company’s warehouse,” the house had a cellar, kitchen and attic, and neighboured that of Noël Jérémie dit Lamontagne and Jacques Leber. Curiously, Jean now declared not knowing how to write or sign.   

Death of Jean

Jean Gagnon died at the age of 59 on April 2, 1670. He was buried the same day inside the parish church of Notre-Dame in Château-Richer. He was recorded as a marguillier, or church warden. [Although the burial record gives Jean’s age as 70, his 1610 baptism establishes that he was 59.]

The burial record reads:

“In the year of our Lord Jesus Christ, one thousand six hundred and seventy, on the second of April, Jean Gagnon, husband of Marguerite Cochon, aged seventy, died in the communion of the Holy Church, having received penance and the sacrament of the extreme unction on the second of April; being a churchwarden and a resident of Notre-Dame du Château-Richer, he was buried in the same church.”

The Inventory

Marguerite would outlive her husband by almost three decades. During those years, she appears repeatedly in the notarial record, managing property, settling family inheritances and disputes, and gradually transferring portions of her land through a series of sales, divisions, and agreements.

On January 19, 1674, notary Paul Vachon drew up an inventory of the community of goods belonging to Marguerite and her late husband. The document enumerated their possessions, which included:

Hearth and kitchen equipment

• a pot/fireplace crane

• cooking pots with their lids and ladles

• a grill/gridiron

• a shovel

• five kettles

• a strainer

• 16 pounds of pewter

• an old basin

Weapons and tools

• a large gun

• another gun

• two sickles

• two scythes

• a carpenter’s chisel

• a hammer

Farm equipment and livestock

• a fully equipped plow with its fittings

• four oxen

• two dairy cows

• two other cows

• three heifers

• four pigs

Grain and food stores

• 50 minots of wheat

• 25 minots of barley

• 4 minots of peas

Furniture

• two chests with locks

The inventory also listed a few outstanding debts and obligations, as well as the land concession document for Marguerite’s property. It measured seven arpents of frontage on the St. Lawrence River by one and a half leagues in depth and bordered the lands of Jacques David and Jean Gagnon, son of Pierre. It was subject to a cens of 7 sols, plus 7 livres and two live capons in seigneurial rente. The document also includes Marguerite’s signature.

Dividing the Cochon Inheritance

Six months later, on the afternoon of July 2, 1674, Marguerite and her brothers Jean and Jacques appeared before notary Vachon to divide a land concession located in Château Richer, in the seigneurie of Beaupré, inherited from their father Jean, who died in 1673. The land measured six arpents of frontage facing the St. Lawrence by one league and a half deep. On the property was a house with two lower rooms, a cellar and an attic, as well as a barn, a stable, a courtyard and a garden. It was subject to a cens of 6 sols, plus 6 livres and two live capons in seigneurial rente, payable to the seigneurs annually on November 11, the feast day of Saint Martin.

Jean and Marguerite relinquished their rights in the three-arpent portion on one side to Jacques, while Jacques relinquished his rights in the other three-arpent portion to them. Jacques's portion was the improved half with the house, buildings and cultivated land. The other three arpents fell to Jean and Marguerite. The agreement also contains provisions intended to equalize the partition; Jacques was to assist with grain associated with the other three arpents so that Jean and Marguerite could develop their portion.

In 1681, Marguerite was recorded in the census of New France still living on the côte de Beaupré (in Château-Richer) with her two sons, Germain and Raphaël. The family owned one gun, nine head of cattle, and 14 arpents of cleared or cultivated land. The household listed before hers in the census was that of her nephew Jean Gagnon, and the one after was that of her son Jean.

Inheritance Disputes with Son Jean

The disputes over Jean Gagnon’s estate had begun several years earlier. On February 24, 1676, notary Gilles Rageot drew up an arbitration agreement between Marguerite, acting on her own behalf and as mother and guardian of her three minor children, Germain, Raphaël and Marie, together with their paternal uncle and curator Pierre Gagnon, and Marguerite’s adult son Jean. A dispute had arisen over what Jean was entitled to receive from his late father’s estate, as well as other claims between the parties. They agreed to submit their differences to arbitrators and to abide by their decision.

On August 9, 1682, Marguerite and her children entered into another partition concerning the division of the family’s land in Château-Richer. Disputes nevertheless continued, particularly between Marguerite and her eldest son Jean over their respective rights and financial obligations arising from his father’s estate. On March 15, 1684, the family again agreed to submit the outstanding issues to arbitration.

The arbitrators issued their decision the following day. After reviewing the family’s earlier contracts, estate inventory, accounts, land divisions and previous court decisions, they balanced the various claims between Marguerite and Jean and determined that Jean ultimately owed his mother only 19 livres and 1 sol, which Marguerite agreed to forgive.

More importantly, they rearranged their adjoining landholdings: Jean received his inherited share of four perches and three feet of frontage beside land he already owned and transferred an equivalent area to his mother. The fence between their properties was to be moved accordingly, and all other outstanding claims between the parties were dismissed. On March 20, 1684, the Conseil souverain formally confirmed the arbitration award.

Settling the Family Property

After the inheritance disputes had largely been settled, Marguerite continued to manage and gradually redistribute the family’s property. Between 1688 and 1696, she appears in a series of notarial transactions involving her children, in-laws and other relatives. These agreements included sales and donations of land, the settlement of inheritance shares, compensation for services rendered by her son Germain, and ultimately arrangements for her own support in old age.

• January 23, 1688 — Property transferred to Germain: Marguerite’s sons-in-law Jean Caron and Louis Gagnier acknowledged that she had fully satisfied the shares of movable property due to their wives, Marguerite and Marie Gagnon. They then sold their wives’ inherited land shares to their brother-in-law Germain Gagnon. Each parcel measured four perches of frontage on the St. Lawrence River by one and a half leagues in depth, and Germain paid 150 livres for each. In a separate transaction that same day, Marguerite sold Germain a one-arpent portion of her own Beaupré property for 600 livres.

• April 3, 1689 — A donation to Barbe Delphine Tardif: Marguerite and her brother Jean Cochon donated two arpents of land at Château-Richer to their sister-in-law, Barbe Delphine Tardif, widow of Jacques Cochon. The property extended one and a half leagues inland and lay between land belonging to the donors and Barbe’s own property. The donation was made in recognition of the “good and faithful services and friendship” Barbe had shown them.     

• May 11, 1692 — Sale to Jacques Cochon and Geneviève Plante: Marguerite sold a portion of her property in the seigneurie of Beaupré to her nephew Jacques Cochon, son of Jacques Cochon and Barbe Delphine Tardif, and his wife Geneviève Plante. The land measured one arpent of frontage on the St. Lawrence River by one and a half leagues in depth and included cultivated land, meadows and woodland. It bordered the property of Barbe Delphine Tardif, and the purchasers assumed the seigneurial obligations attached to the land.

• June 3, 1692 — Compensation for Germain’s years of service: Marguerite formally acknowledged owing her son Germain 1,000 livres for the many years of service he had rendered her following his father’s death. In satisfaction of this debt, she transferred to him a parcel measuring one and a half arpents of frontage on the St. Lawrence River by one and a half leagues in depth. The agreement also protected Germain’s investment: if Marguerite’s heirs later attempted to reclaim the property, they would first have to reimburse both the 1,000 livres and the value of any improvements he had made.

• June 3, 1692 — Property in exchange for lifetime support: In a separate act executed the same day, Marguerite transferred another parcel to Germain, this one measuring one arpent of frontage by one and a half leagues in depth and valued at 800 livres. Instead of paying the price in cash, Germain undertook to support his mother for the remainder of her life. His obligations included food, lodging, and heat, care during illness, clothing, and, after her death, responsibility for her burial and prayers for her soul.

• January 12, 1693 — Sale to surgeon Jean Navers: Marguerite next sold an habitation at Château-Richer to Jean Navers, a surgeon, for 1,300 livres. The property measured two and a half arpents of frontage on the St. Lawrence River by one and a half leagues in depth and included cultivated land, meadows and woodland. It bordered land belonging to the heirs of Jean Gagnon and property then held by Germain Gagnon. On March 11, Marguerite formally acknowledged receiving the purchase price and released Navers from any further obligation.

• November 5, 1696 — New arrangements for Marguerite’s care: In the last known notarial act concerning Marguerite before her death, she, Germain and her son-in-law Jean Caron reorganized the arrangements for her support. Marguerite was to live with Caron and her daughter Marguerite Gagnon, who would provide her with food and lodging whether she was healthy or ill. Germain agreed to contribute 25 livres per month toward her upkeep and remained responsible for supplying her clothing, including a new robe de chambre and a chemisette. Although Marguerite had signed earlier notarial acts, on this occasion she declared that she did not know how to write or sign.  

Death of Marguerite

Marguerite Cauchon died at the age of about 79 on June 24, 1699, at the Hôtel-Dieu in Québec. She was buried in the hospital cemetery. [Though the patient register records her only as “Madame Gagnon,” the PRDH, Fichier Origine, and René Jetté have all attributed this record to Marguerite Cauchon.]

Gagnon Heritage

Several plaques honour the history of the Gagnon family. In 1960, a commemorative plaque was affixed to the church of Saint-Aubin in Tourouvre in honour of the Gagnon brothers.

In Canada, a plaque marks the place where the Gagnon brothers operated a store in Québec City's Lower Town in 1651. It is located in UNESCO Park.

Another plaque was erected in Château-Richer in 1940, located at 8754 avenue Royale. 

A short French-language film also explores the history of the Gagnon name in Canada:

The Beginnings of a Canadian Family

Jean Gagnon and Marguerite Cochon belonged to the first generation of French settlers who transformed the shores of the St. Lawrence into permanent communities. Coming from different regions of France—Jean from Perche and Marguerite from Dieppe—they married at Beaupré in 1640 and built their life at Château-Richer. Jean combined farming with commercial activity in Québec, while together they raised a large family whose lives became firmly rooted in the growing colony.

Jean’s death in 1670 left Marguerite a widow for nearly thirty years, during which she continued to manage family property, navigate inheritance matters and provide for her children and her own later years. By the time of her death in 1699, the family they had founded had been established in Canada for almost sixty years. Their story reflects the experience of New France’s pioneer generation: migration, settlement, hard work, family alliances and the gradual creation of a society that their descendants would call home for centuries.
