Hello,
Your information appears inaccurate.However I am guessing that your grandmother's name was Una Britton.
Her parents were Patrick H Crennan and Annie Laherty. ( my grandparents). if this is correct, then she is my late Aunt. She had two sisters Evelyn, Carmel and three brothers Joe, Kevin and my father Noel. They were from Abbeyleix, Co . Laoise, which is where I was born. Does this make sense to you? Please get back to me if it does.
Regards
Ann
