In reponse to
Plauts looking to discover their family history, I can add some informattion.
I am Rodney Plaut now living inSydney Australia, originally from South Africa, and my grand parents were from a town in Germany.
Ralph and his brother Max moved to South Africa before WWII.
The had a brother and a sister and a half brother who all movet to the UK.
The common measure of relation seems to be Gunter to whom I too am related.
Apparently his wife researched the family tree, many generations back, but all our attempts to buy a copy have failed (I don't know why).
If any one has more info for me, I would love to receive it.
