Shalom to all,

I'm new in this Sig.

I'm looking for any help in locating a living person in Vienna Austria.
His name is Gedalia GROISMAN, he should be living in Vienna.
I searched the Austrian telephone directory and found a man by this name
[Gedal] . But can't be sure this him, we phoned him - he didn't answered.
Is there a way to locate him through the Jewish community in Vienna ?
Or if there is another way locating him ?

Any help will be appreciated.
