Francois Sirois dit Duplessis: Establishment in North America


Previous Section

 Next Section

In 1632 the colonies in Canada and Acadia were returned to France by England  in a treaty concluded in St. Germain-en-Laye de Paris, a town on the outskirts of Paris, about a dozen miles from the city center. St. Germain dated back to the twelfth century and grew around an old royal residence near the Palace of Versailles. It was likely in this town, around the 1670's, that Jean Sirois dit Duplessis, the earliest recorded ancestor of the SIROIS DUPLESSIS families of North America,  married Marie Thérèse Angèlique Dumont.  About 1680 they had a son -- Francois Sirois dit Duplessis.

Meanwhile, far away in New France, on the south side of the St. Lawrence, about 80 miles east and down river from Quebec city, eleven French Roman Catholic families had settled by 1681 in the Seigneurie de la Bouteillerie, an area that became known as Rivière Ouelle.  It was here, probably sometime between 1700 and 1710 that Francois Sirois dit Duplessis settled.  He likely came as either a farmer "recruit" (engagé) or a fisherman. The engagés were indentured persons, who held a type of contract with free passage but their first obligation, of course, was to work for a period of time to pay off the cost of the trip Bergeron p157.  There is no evidence that Francois' parents Jean and Marie Thérèse Angèlique accompanied him or in fact ever crossed the Atlantic.

We know little about Francois before he established himself in Rivière Ouelle. We do know he could sign his name, indicating some level of schooling almost surely received in France. 


 In the year 1713 Queen Anne of Britain emerged victorious over Louis XIV of France, and by the Treaty of Utrecht received full dominion over Newfoundland and all of Acadia.  While France retained Quebec, Isle Royal (Cape Breton) and Isle St. Jean (Prince Edward Island), her power in North America was drawing to a close - a development that would in time have severe repercussions on Francois' descendants.  Of more immediate import to Francois in the year 1713 was his marriage.  


In 1708, Marie Anne Thiboutot, daughter of the late Jacques Thiboutot and  Marie Boucher, married Noel Pelletier. Ten months later they were blessed with the birth of a healthy baby girl, Marie Anne Pelletier.  The following, taken from the SIROIS DUPLESSIS Family BookCerto-Ahearnep8, indicates that young Marie Anne Thiboutot was soon widowed. 


A dolphin fishing society stated in Rivière Ouelle in 1709 among certain colonists. [After the owner of La Pointe de la Rivière Ouelle, Pierre Dancosse, died] the title holders of "La Pointe" began a feud with their competitors for dolphin fishing rights.  One of their competitors was Noel Pelletier... who had married Marie Madeleine Mignot [parents of Noel who married Marie Anne Thiboutot] Both father and son died pre 1713 leaving the widow Mignot feuding with the Dancosse heirs and leaving her daughter-in-law, Marie Anne a widow with a young child. For the widow Mignot to sill be active in that fishing society, a document states she needed "un homme capable" to replace her deceased husband and son for fishing rights...

Two widows then, both needing a "capable man", one to hold fishing rights, the other to provide and care for herself and her young daughter.  It appears that  Francois Sirois dit Duplessis may have been the one to fit the bill On the 11th of November 1713 a marriage contract was written.  It is transcribed and translated below with areas of note hilited.

De ce anquis interprette suivant l'ordonnance...

Before Etienne Janneau, notary, established in the Seigneurie of the Boutellerie., Port?Joli, Kamouraska and Rivière?du-Loup; the undersigned witnesses were present in person: 

FRANCOIS SIROIS Du Plesy, son of JEAN SIROIS Du Plesy and Marie Thérèse Dumont, alive and living in St. Germain (En Laye), diocese of Paris, both living...(four words illegible)… esquire; and Francois Autin and Marie Boucher, stipulators for Marianne Thiboutot, their daughter.
This marriage contract is thus made.

Let it be known; the witnesses for SIROIS: Pierre Albert and Pierre Hemon. The witnesses for Marianne Thiboutot: Francois Hautin; her stepfather, and Marie Boucher; her mother. Jacques and Pierre Thiboutot; her brothers, Jean Francois Pelletier; her brother-in-law, Pierre Roy; her brother-in-law, Jeanne and Geneviève, and also Marie Thérèse Hautin; her sisters. All relatives and friends of the said parties. This marriage contract is thus made.

Let it be known that the said FRANCOIS SIROIS and the said Marianne Thiboutot have promised by law to take each other in the name of marriage and vow to have their marriage solemnized in the name of the Holy Roman Catholic and Apostolic Church. The future spouses are advised by their parents to be as one with all their current and future personal property, to not keep things separate one from another, and to remain free of debts as they continue in all favour and …(illegible)… marriage.

Out of the kindness that the said groom has for his bride, he will give her a dowry of five? hundred livres and the best..(illegible).that will be found in the said community. It will be the wife's choice, if in case the husband dies before her, to divide or rent her dowry, free and clear of all debts, in case there are no children born or left from their marriage. The groom promises and is bound that, in regards to the child of the bride's first marriage; he will nourish and care for her until she marries. Out of the kindness and affection the bride has for her groom; she gives him that part of land …(damaged)… belonging to her, located in the Seigneurie of the Boutellerie, arising from her inheritance. So the said parties swear and promise.

Done and passed in Grand Kamouraska, November 11, 1713, in the presence of all the parents and witnesses who have declared they neither could write or sign, except the groom, Jacques and Pierre Thiboutot and Pierre Roy, who have signed with the said notary. The wife has declared she could not sign…

This according to the ordinance...


From this contract we note that:


As of Nov 11, 1713 Francois' parents Jean and Marie Thérèse were alive and living in France (as far as he knew)


Francois gave his bride a generous dowry of 500 livres


Francois received land from his bride  from her inheritance


Francois signed his name

On the 28th of November 1713 Francois and Marie Anne were married in the parish church of Notre Dame de Liesse at Rivière Ouelle. From this document transcribed below we note:


Francois age is given as 33, placing his date of birth at about 1680


Francois father Jean is listed as deceased. 


In the marriage contract written just two and half weeks earlier Jean Sirois was listed as being alive.  Perhaps Francois received word in the interim period that his father had passed away. Had he sent notice to France in the spring or summer of  his forthcoming marriage?
