I wish I could say it helps, though I do appreciate you taking the time to look and post.
I know nothing of my KILMARTINs or any of the related families, after my relatives all emigrated from Ireland to Glasgow in the 1840's thru' the 1870's. (What? No spuds?)
The only info' prior to that time is, the names of parents of various Glasgow kin as they applied for Poor Relief in Glasgow in the 1880's and 1890's. In some cases, their parents were mentioned, but invariably as "deceased", Ireland.
So..bottom line...I know of NO relatives left in Ireland.
