Ralf Gustav Wahle.
Birth date 28th April 1932 Germany.
Moved to Australia in 1952. Gave birth place as Hamburg on immigration record.
Returned to Germany around June 1966 and this is the last information that i have on him.
Ralf knew that my mother was pregnant but wasn't encouraged to maintain contact and might not know of my actual birth for example if I was male, female or my name.
I am Australian and live in Australia and so access to German information is tricky.
I have done searches in Ancestry.com and MyHeritage but found nothing so far of help at the time of writing.
Any information would be most valued.
