Hidden history

by Richard Fischer
(England)

Hi I’m trying to trace my dad’s past but I’ve fallen at the first hurdle. My dad is 96 and lived in Strasbourg during the war, his parents (my grandparents) were bombed. He was born in Forbach in Feb 1928, father: Louis Fischer and mother Françiose.
My dad seems to have multiple names on his documents ranging from Henri, Henry and Henry’s.
If anyone could possibly give me some suggestions I’d really appreciate it.
