Hi just reading through the details.
My mother was born in Clara, County Offaly 1940's, her birth name being Bridget Byrne. My Maternal Grandmother, her mother was Kathleen Byrne and my mother was born illegitimate.
Kathleen once the child was born, was sent to England in 1947ish, my mother remained and was cared for by her maternal grandmother who's surname was Coughlan/Coughlin. When my mother was 3 she and her Grandmother moved to a farm cottage on a farm owned by the Fleming family in Ballycumber. There were a lot of male children of the Flemings I have been told, I am wondering whether this is the same Fleming Family that are connected to you?
