Thank you Danielle. I'll fix the link in my citation. Here is what we know and think it says from other sources (including Tanguay and PRDH and FichierOrigine).
parties and parents:
Jacques Achon, son of Jean Achon and Hélène Regnault, probably from Chambon
Marguerite, daughter of Pierre du Sainte Foy and Marie Andrieu (might say following names that parents are from the parish of St Denis in the diocese of Rouen? Migrations says it is St Denis de Duclair which google says is 11 miles west of the center of Rouen)
would especially like to know if it mentions any parishes and for what events and also if it says any of the parents are deceased or says where the parents are from.
dower: likely 150 livres although one other source says 200; would like to know if it mentions anything other than the livres as part of the dowry
Ages of any person: does it give any?
Jacques occupation: fichier origine says he was a migrant who arrived in 1664 and that his father's occupation was Journalier
Fichier Origine says that according to the contract, the wedding is to take place at Ste-Anne-de-Beaupré
In the upper left margin of the first page the date says 4 Dec 1667 which is the date most sources use for the marriage, but in the first paragraph of the text, it looks like it might be 7 Dec. What do you think?
