Hi - What a story. Possibly born out-of-wedlock in Corsica and then taken home to Switzerland where his mother married and he was adopted. In later life he gave his birth as Switzerland.
The birth date is January 5, 1897 and it is possible that his birth name was Paul Fulier. When he emigrated to USA in 1920 he went by the name Furler. Prior to becoming a US citizen he changed it to Fuller.
If I am able to search for birth records for a particular date - I would probably search only on his forename Paul.
Can anyone point me to a source for hunting this down?
Thanks!!!
