My poor old Dad never knew who his father was. He was told he died in WW1 but that person died three years before my Dad was born and the sister who came before Dad can't be his either but we know for sure that the three siblings before both of them definitely were his. I am on Ancestry as I thought I might get somewhere but haven't got far. Dad was from a poor family and his grandmother was described as a washerwoman/pauper.
My Mum's family is huge and although many emigrated to America (mainly Philadelphia) loads stayed in Ireland. They have all done very well with grandchildren and greatgrandchildren including an olympic champion, a TV actress, an architect who worked on the highest building in Dubai, a teacher in Japan, a judo expert, a champion basketball player, several teachers, business people and many of them have built themselves very beautiful homes.
