The chances are good-to-excellent that you are researching the same general
line, but you can't pinpoint it to an exact person. When you have to
approximate birth years, it makes it more difficult to estimate, but it seems like there
might be time for another generation. His William could be the son of a John
who was the son of the John who disappeared.

Other factors might give additional strength to a connection, for instance,
if there are no other Thomas families in the vicinity, or if your haplotype is
uncommon.
