Hi Christine: I sent you an e-mail but got no response; hope you see this. The date and place of birth you list in your message if believe is not correct. That is, not if this is the same Isaie that married Henriette Couture or who was the son of Pierre Racicot and Josephte-Lizette Beaupre.
Pierre and Lizette got married in 1831, so I doubt that Isaie was born before that, given the mores at that time. Also Isaie married Henriette in 1851 which would have made him 35 when he got married, if he was born in 1816. I have a picture of he and Henriette and they do not appear to be older than 18 or 19 years old.
Also, I doubt that our Isaie was born in Ontario, but more likely in Quebec (Napierville, St. Cyprien, or Boucherville). There is another Isaie Racicot whose parents were Antoine Racicot and Lucy Hodienne who Gilles Tourangeau has listed as being born on 2 Oct 1816 in Michigan, Wayne Co., Detroit [Ste. Anne's], which is close to Assumption, Sandwich, ONT. I plant to do further research on his birth date which I believe would be closer to 1832 or 1833.
