Hi Joy, What research have you already done - that might help others help you?
What information are you searching for ?
You know that George SKINNER was a U.S. Citizen
Do you know When? Where? he was born - knowing that would help others identify your George SKINNER - from others.
George SKINNER enlisted in Canada during WW2. You don't know why? - Perhaps the opportunity to enlist - was not available in the USA at the time. Perhaps there may have been a problem qualifying in the USA for the service that he preferred.
George SKINNER was in the London Area from December 1944 - January 1995.??
Did he pass away in 1995? or go elsewhere?
If he passed away - Registration of Death - may be helpful.
Perhaps an obituary was published.
Have you obtained service Records ?
Have you searched U.S.A. Census to 1930?
Have you searched USA Social Security Index?
Cheers & Good Luck, Stella
