'How would you know that? It's very common in the US for people to have family stories about First Nations heritage, and quite a few are true, but generally much farther back than they realize.'
What sort of situations?
Google tells me Europeans started colonising in 16c which in the scheme of things isn't that long ago.
Do you mean indigenous women being raped?
I don't know loads about USA history tbh on this topic past slaughter, land being taken, etc etc.
All kinds, but there was a lot of intermarriage between Europeans and indigenous peoples. (And yes, First Nations is usually used in Canada, and American Indian more often in the US, but for most purposes other than legal they are interchangeable.)
In the US in particular, many families have stories about having a great grandparent or something similar who indigenous. But the stories often seem to get passed down as, say, a great grandparent, but over a few generations that really means a great-great-great grandparent, but that part of the story doesn't change. Or, there ends up with a mix up between different tribes this person belonged to, or sometimes it might even be a mix up around the person being a totally different racial minority altogether. Some of the stories are just not true, but people think they are.
The Metis, the group this lady claimed to have ancestry from, are a distinct cultural group that developed from intermarriage between early French fur traders indigenous women. But while it can have very specific meaning in terms of ethnicity, and also a specific legal meaning in Canada that has implications in terms of indigenous status and land claims, in other contexts it can be a very loosey-goosey term that just indicated some mixed ancestry, somewhere way back.
There are lots of people with some First Nations heritage that somewhere along the lines lost their indigenous status - which is a legal construct - due to intermarriage, or because of the limits bands put on members, or for other reasons. They have real ancestry but may no longer be eligible to have that recognized, or they don't want to. People whose families lost status but want to have it recognized need to be able to show certain things demanded by the government or the band in question, and that isn't always possible. Though it's a lot more common for people to try and do this now than it seemed to be even 30 years ago.
