Hi Bill, I checked your message history to see what else you might have on this family. Oh, my, I think each post got better. I suggest you use the one from the Indiana forum, it contains sooooo much on these people. It surely narrows down to who they are and where they came from. Have fun with the research in Ireland, I hear it is a bear.
You might try the Mills forum, in the box marked Search This Forum, type in Ireland, there are 137 matches, but some will pertain to the same original posts. I would browse through them, click and see if anyone has Isaiah. Or you could try Isaiah in the search box, too.
