Much much much work has gone into analyzing the evidence for the spouse of Augustine Bearse-3.
The serious analysis started in the late 1930s when the "father" of modern genealogy-- Donald Lines Jacobus-- published an analysis of a manuscript that had been submitted to the Library of Congress in 1930 by one Franklin Bearce-45.
We've converted that article into a point-by-point analysis here.
Despite this analysis, and despite the lack of any solid evidence, descendants hold onto the dream that they are descended of an Indian princess. Google "Mary Little Dove Hyanno" and you'll see...
While her supposed father (Chief John Hyanno) and grandfather (Chief Iyannough) were recorded as real individuals in documents from the time period, I have yet to see any solid evidence documenting ANY of their descendants (or ancestors, but that's another g2g thread that I'll let someone else take up...).
Mary "Little Dove" Hyanno has been marked as a likely fictional character.
I therefore propose that she be detached from any parents.
