Since you have had DNA testing done by Ancestry.com, you might consider loading your results to gedmatch.com. I don't think Ancestry.com has the best system for comparing results among individuals, and gedmatch.com would allow comparisons with people who have tested with other services.

While I have some distant Harvey cousins, nothing else in the Wyatt genealogy that you outlined seems to fit. However if you were to upload your test data to gedmatch.com, I certainly would want to do a comparison.
