Quotes from article:

Champlain and his extended family are among thousands of people removed from American Indian tribes in recent years, often amid tribal squabbles or when a casino comes to town.

There are 562 federally recognized tribes, and tribal governments are not required to report citizenship decisions. But the number is in the thousands.
