Hey cousin Margaret!
She and I are 2nd cousins, 1x removed!
I have the book she refers to, what a treasure! I've inputted a lot of it into my Ancestry tree. Darby Doyle is here:http://trees.ancestry.com/tree/23882208/person/1532420718
If the link doesn't work, check out the tree in my profile with Doyle in the name and search for Darby!
