I am not sure why I asked that. My contact's trail led back to Ireland. Despite being in the same general area, they are entirely distinct from the line that married into the Cleals. I didn't think that "Tayler" was an Irish spelling. My contact thought that they originated in Scotland.
I found a Tayler born in Corop, Victoria. He doesn't seem to be one of mine. The number of false identifications on the mother's side has made me very cautious.
