Surprising indeed. I put some of the relationships we have worked out on Ancestry to see what trees it would link with. It is interesting that the 26 Feb 1710 Braddan baptism record for William Corkill has been incorporated in a few different family trees with radically different descendents. I think what we have found thus far gives ua a pretty good claim on using that baptism record. But, I admit it still isn't locked down.
