This profile needs assistance to connect Nancy to her Irish/Scottish roots. My family file links her to a John Buchanan and his wife Catherine Black. Family Tree links her to a William Alexander Buchanan and his wife Katherine Blair. The only things we all agree upon is she is from County Donegal and a protestant.
I have some unsourced myths that she is the Aunt or Great Aunt of President Buchanan, but again that information is unsourced. Her only child according to what I can find is Hugh Caldwell. Another unsourced myth is that she did not make it to America, assuming she died just before leaving, or on the voyage. However, FAG says she is buried in Lancaster, PA.
Is there an Irish protestant roots finding group here? I need source materials linking Nancy to her birth family.
