I have a feeling that that's gonna be the case where finding Granddad's half sister is concerned. I spoke to him yesterday about finding her etc and again all I got was that she would be the same age as his oldest sister whom was born in 1920. The story goes my G Granddad had two women on the go at the same time, both women fell pregnant around the exact same time, G Granny told him she was pregnant so "gunshot" wedding happened very quickly not long after that my G Aunt was born, a short time later the other woman" traced my G granddad down to tell him that she was pregnant and shortly (weeks) after that his other daughter was born, G Granddad was informed and after that it was not spoken about, my Granddad remembers meeting her, as my G Granddad must have taken my Granddad to meet her as he remembers her telling him that she was his sister but her mum wasn't his mum, my Granddad thinks he would have been about the ages of 10 to 12 years old, but again he wasn't allowed to talk about her with anyone else in the family as G Granny was livid with him for having dated her and the mother of his other daughter at the same time (she probably was shocked about it too, Thank you everyone for all your help and idea's I greatly appreciate everything you have all done for me try find her. If anyone else can think of anything to aid me till Reg House (scotlandspeople is too expensive to do a load of trying to find her on there...
Thank you all again for all the help
