I am trying to get in touch with my mother or half brother. My Mother is known as Alice and the last time we met she was working in homes as a nurse for the mentially ill and my brother is known as Alisdair he was also born in Edinburgh but moved down south shortly after. The last time we met or spoke was almost 11 to 12 years ago my mother had just recently split from an other marriage from the name of a man called Stuart Bond. When my mother and Stuart were married Stuart Adopted my half brother that is wht he may still have the surname of Bond.They all lived in a small town called Broughton near the Humberside area. My mother also has/had two brothers of the names Sammie and John i have no idea where they could be now. Alisdair my half brother will be 27 or 28 years of age now and my mother Alice will be in her early to mid fiftys.I dont know if they stilll live in that area as above or they may have moved again as my mothers side of the family lived up and down the Country from Scotland to the south of England.
