But I cannot find out about my Dads older Brother
This would be your uncle, yes ?
To be honest I don't know how to find him.
But. He may still be alive and in the phone book.. He may have had children who carried on the family name..
It is possible to search the phone book, but you need an address.
The easiest way to find people with the same name is to search: nasza klasa
I would find a town or city website (for the town in Poland or nearest big town) with a forum and leave a message. Some Polish city websites also have genealogy help. And more important... pages in English
There is a link somewhere on here for old polish directories. They might help with an old address.
Do I understand correctly. Your dad's sister has no info on you dad's brother (her brother) Or is your dad's sister now deceased.
I'll have to have a little think about this, but unfortunately on Monday I'll be off-line for a month.
