Wow Abigail - This is amazing! If I'm reading this right, according to Richard's reply as well as your own, I now have four more generations to add to my tree!
My G x 3 Grandather, Thomas b c 1780, is the son of James b 1743 (and Margaret). James is the son of John b 1686 (and Abigail). John is the son of Oates b 1647 who is the son of Finlae b 1606.
Thank you to both you and Richard and all the people who put in the hard work in the IOM! Although Cretney is a fairly recent addition to my tree, it is only one step away from my own name.
