sandrak on Family Tree Circles

I am looking for my fathers sister. Her name was Doris Balinsky born September 1928. My father was called Ivan Edwin Balinsky born in St Martins London September 1932. He was taken to Lamorby Children's home till 1940.

He was then moved to Bedford House Stepney London when the war broke out. I have tried the samaritans and was only able to find out his sisters date of birth. Their mother was called Ada. Unfortunately he has not seen her since she was around 14/15, so we have no idea of my fathers background/history, or whether she is still alive, whether she married, emigrated, has any living relatives. Any information that may come to light would be warmly received. Thanks for reading this.
