Wow thanks for all your help. The george W Lacey mentioned in the last post was George Isaac Allens adopted son, he was born out of wedlock to Georges wife Mary Lacy. I did find the census's you all mention, but If these are the correct ones george would of been listed using his middle name?
George Isaac Allen is the father of Sarah jane Allen born 1901 died 1975.
Sarah Jane is the mother of the friend i helping. So he is pretty certian on names, he does have George and Marys marriage certificate. To confirm. This man is a complete mystery to me. I have contacted my friend again and asked for more info like did he know georges fathers name?
Once again thanks this is a great site, if any of you come up with anything else much appreciated.
have a good day
