That's strange that AncestryDNA doesn't find more Native in you because I have more Native-American on Ancestry than on 23andme. Sorry to hear about your recent diagnosis.
I’m assuming they didn’t display it because it’s common knowledge pretty much that Acadians are a mix of French and Mi’kmaq.
Although that’s not always in genetics since not all French people married Mi’kmaq people, obviously... for example if your ancestors lived in a place that was previously uninhabited before European arrival, as is the case for Acadians in Quebec, who mostly live on the Gaspé Penninsula and the Magdalen Islands... the Magdalen Islands were uninhabited and Gaspé is Mi’kmaq for “Newly acquired land” so there probably weren’t very many indigenous people living there in the 1600s.
I think the mixing was more cultural rather than genetic. From what I learned about that time, only rich/powerful Acadians married rich/powerful Mi’kmaq, usually for the purpose of securing trade deals and stuff, while the rabble of both cultures didn’t mix as much... because they were working class so they were busy and hence mated with people close to them.
As for the diagnosis: “meh”. I mean yeah, there is a good chance I will be dead within the next decade (most people with it die in their 40s and I am 38) but you know what? I lived an OK life, seen and learned a lot of things, and went on some great adventures, so it doesn’t bother me. Actually it’s good, because I don’t have to put money away for retirement or worry about that shit anymore, I can just burn through it now 😂😂😂
