PRDH lists this individual as the child of Jacques Daigneau and Thérèse David, born in Boucherville in 1775, likely due to his marriage record (in Varennes, 28 Jan 1799) showing him of majority age. However, it lists him as 52 at time of death, making it possible that he is the Jacques born to his father's first wife, Françoise Aussant, on 27 Sept 1771.
The other Jacques (Daigneau-37), the one definitely borne to Jacques and Therese, is listed in PRDH as born in Boucherville on 3 July 1781 (PRDH Individu #590283).
Where would a marriage contract from Varennes have been located at that time? I think I've looked through all the available notaries in Ancestry and haven't found them, but perhaps there is somewhere else to look.
Finding the marriage contract of this individual could assist in clarifying parentage
