I'm also a potential descendent of Jacque/James and Marie. My GG grandmother was Margaret (sometimes listed as Marguerite) Robinson from Quebec. She was a woman of colour (either black or mixed) born August 1812. She met my GG grandfather in Montreal and they emigrated to Port Hope, Ontario, marrying there and finally settling in Centralia Ontario, just outside of London. Many members of our family have undergone DNA testing and consistency we're showing mid/west African ancestry. The story in our family was always GG was native. There's no native showing up and I've now got a photo of her, as well as her eldest daughter and youngest son (my G grandfather) which definitely suggest African vs native ancestry. I'd like to explore this further. Have you done any DNA research?
