I'm looking for a marriage between a Joseph Fournier and Mary Angela (probably Angele or Angelique), probably between 1820 and 1836, but possibly up to 1851. They signed a marriage certificate in 1852 in Illinois for their daughter Mary Octavia (probable Octavie), but this does not prove that Mary Angela was her biological mother. What I actually want is to trace Mary Octavia's biological mother.
A Joseph and M__ Fournier lived in the same town in Illinois in 1850, without Mary. This Joseph was 50 years old in 1850 (probably approximate), and M_ was 45.
Mary might possibly have been living with two younger siblings with another family in Matawaska, and she certainly isn't anyplace else in two countries. Mary Octavia Fournier was born around 1833 to 1836 in Canada, and possibly on May 1, 1833.
I suspect that this family belonged to a clan of Fournier's who lived in Matawaska, St-David adn St-Basile parishes. There was a Joseph living in the neighborhood of the Mataswasca or whatever River the right age and struggling socioeconomic status, and the Joseph of each place followed Basile Fournier, who actually was in both places, around by the tail, even though this Basile allegedly had no brother named Joseph. Maybe they were cousins. The only other Fournier to live in that part of Illinois in the right time period was a distant cousin of Basile's.
If your book happens to verify the parentage of Mary Octavia Fournier into the bargain, and even provide her some siblings, that would be Cowabunga!
Thank you very much. :)
