source. But the ancestor of mine that this started with is from several
pretty well documented sources.
One is a book my family published in 1926 that lists her, and some specific
information about her. Then this information was duplicated on the web, but
from different sources (by that I mean, from people searching different
families than mine, that she is a common ancestor to).
I usually check what I have against reputable sources (census, newspapers,
church records) but this line was pretty well researched (lots of corollary
information, footnotes, etc.), so I trust it at least as far back as around
1500. Then the dates and names are getting a little hinky.

You got back into the 1300's? Did you or someone in your family do the
research? Just curious as I found some alleged connections to my family on
the internet of which I am skeptical.
