Lines of the Coffey, Baillie, and Wilson families are also found in Indiana. In the 1800s they commonly went between the "Bowling Green" area and Highland, Co. Ohio.
However, an odd element is that, at least in Indiana (some in Kentucky)...Wilsons are very intermarried with families that come from the "East Indian" Weaver family.
I cannot speak for the Coffey family personally but I have always assumed they were somehow Romany related simply because I run into the name so often...and I only have Romany, East Indians, and Jews in my family (and rather well intermixed at that).
oh...very few Baillies lasted with the original spelling. The more common American Bailey spelling is how you will find them.
