The Henry Kornhauser Family Home Page

I am researching my family history. I found that my great grandfather, David Kornhauser, was born in Tarnow, Poland in 1861. My great grandmother, Kate Berkelheimer was born in Nowy Sancz, Poland. David's parents Joseph and Chaja Kornhauser lived in Tarnow, but I don't think the were born there. Joseph's father and mothers names are Isadore and Kate Kornhauser. Isadore was born about 1812.
If anyone out there can add anything to my research, it would be greatly appreciated.
