Hi - my latest William Collister my great grandfather (born 1857) married Margaret Rothwell. By that time he had left the island and was living in Liverpool. So I guess it is not the same one.

The previous Williams were William born c1788 and who married Martha Fargher.

William born 1754 who married Catherine Costain

Don't know if you can see any connections at all - would love to hear if you can!
