I haven't had much luck in the past 3 yrs. I know my Tierneys were from Killeenadeema, as all 3 siblings ( James, Thomas & Nora) were listed as being natives in their obits.
Most of my info comes from Tierney daughters and nieces before they died some 40-odd years ago.. I've tried to back up family history with primary sources, which I have posted on my Ancestry tree. If your Tierneys were from the same Parish/village, my guess is that we are related, though the relationship isn't visible before the early '1800's. My Tierneys also lived for a time in Clifden and Inishbofin before arriving in NY in 1853.
