Thank you so much for your help, it is very much appreciated.
I do not actually use any software, I have just been using ancestry.com to search and build the family tree.
I started out last year for my Mother, because after all these years she finally wanted to know her roots, as she never met her father and other siblings.
My mother was a war baby you see and was actually brought up by her grandmother. She never knew her father and believed he never wanted to know her, hence the reason she never looked for him.
So it came as a massive shock to her when we received her fathers military records, that he did acknowledge my mothers existence and actually had a copy of her birth certificate in his file and had tried to find her himself.
I thought it would be easy to trace the family tree, what with all the information that was supplied by the military, but actually it has been really difficult.
Anyhow, thanks again, and as I say, all help is extremely appreciated.
