So my grandfather (last name of Buffalo) has claimed for years that he is a descendent of Buffalo Hump. I've been searching for sources to find out more about his children to try and trace it down to today but online sources are very rare.
I'd just like to be able to present him with a lineage to him.
A quick mod reminder to OP and potential respondents of this subreddit's personal privacy rule:
Privacy
Certain questions can lead to privacy concerns, and with this in mind, there are specific inquiries that we prohibit where, in our estimation, possible privacy concerns override the historical value of the question. As such, we do not allow questions which pose possible privacy issues for living, or recently deceased, persons who are not in the public eye. The cut-off for "recent" is 100 years, but even if a question does not meet the exact criteria above, we may remove at moderator discretion if we believe there nevertheless remains certain privacy concerns.
I'll allow the question, but please restrict discussion to public figures, or any person dead >100 years. Thanks!
