Dear Sarah,
How do you handle Indians who were given names by their captors? 2 examples:
1: I have a Dine friend ( Navaho ) whose ancestors were given the name "Cambridge" because the particular Army sargeant who was checking their existence off on a list during the "long march" was named that.
2: Our family website ("Axtell Family Organization") mentions a Nez Perce ( Stephen Axtell ) who was given our name because the local county clerk didn't like his Indian name.
A separate American Axtell lineage started in 1885 when a Nez Perce (pronounced nezz purse) Indian in northern Idaho took the name Stephen Axtell to be eligible for a grant of land. He had a son named William Whitman Axtell who married Nellie Moody in 1923. Their only child was Horace Percy Axtell (born 7 Nov 1924), named after Horace Moody, an uncle, and his father's friend, Percy, the postmaster in Stites, Idaho. Horace's Indian name is "Isluumts", after his grandfather. Horace is a great-grandfather, so the Stephen Axtell lineage has 6 generations now.
BTW, I use the term "Indian" because that is what all my Indian friends use.
