Peter, I've just pick up your message regarding Mary Ann Kinsella. I think we are on the right track, as Nellie Britton (nee Purcell) was one of Mary Ann's children, and older sister to my mother Peggy (Margaret).
My reference to Garden City was from a childhood visit, not sure of the actual year, maybe l948 - l949. Our family stayed in a farmhouse in Ballymoney, and Uncle Peter Kinsella picked us up, in a pony and trap, and took us to Garden City. I also remember someone in the family breeding Greyhounds.
