Germany

[denisegenes]

I wonder if anyone can help me trace my Gt Aunt's Louisa's family in Germany?   She married a Martin Leske, aka Rudy, in 1911, but I am not sure how soon after their marriage they moved to Germany.  They had two children Elsa and Eric.  Eric, born in 1920, died 24.9.1947. Elsa I think must have married someone called Bartke, as one of our family had a communication from a young Wolfgang Bartke in 1960, saying that my Gt Aunt was his Grandmother, but I have been unable to trace him through the address I was given.
Any help would be so much appreciated.
Fingers crossed!!
