Ann Tierney is a puzzle Tierney-1995. I will appreciate new eyes looking at her parents. Are they Peter and Ann or William and Hannah? (references for both are on her profile)
Her two children are called William and Hannah, so I favor that couple.
But she is named Ann, possibly after the Ann and Peter couple.
But I have noted on unrelated profiles that a woman named Hannah may sometimes appear as Ann.
I suspect that part of the problem isolating Ann Tierney is that she married John Quinn and there are many men by that name.
Thank you for any hint, no matter how small.
