UPDATE: I am (still & desperately) seeking information on the birth & families of Antoine Donais* & Harriet Gifford/Grifface**
Antoine Donais (*aka Delonie; Delonay; Delonoy) was b. abt. 1813 (possibly Quebec???); he was in the Mackinac Island/Cheboygan Michigan area by 19 Mar 1831 when he married Harriet Gifford (**aka Margarith Griffith; Margarittoe Grifface). They had (at least) 2 children, both of whom were baptised at St. Anne's Church on Mackinac Island:
1)Elizabeth Isabellam b. 02 Dec 1833 (again, many spellings) who married Moses Rapin on 23 Sep 1851.
2)Antoine b. 31 Oct 1835 and m. Marie Louise Lessieur; Magdeline Aslin & Jennie Taylor. Antoine and Magdeline aremy 2nd great-grandparents.
*The following are all documented variations of this surname: Delonoy, Delonais, Delanory, Delaunais, Dolinis, Delannay, Donet, Dellone, Doaner, Donor.
I have gathered a good deal of information on both children, Elizabeth and Antoine. However if anyone knows ANYTHING about the 'senior' Antoine and Harriet/Margaret or if anyone is willing to do paid research on them, please let me know--I've been at this same 'brick wall' for YEARS, and can't find a clue.
