I am seeking information on a Katarzyna Bien who was married to a Wojciech Ostafin. They were both from Austria. They would be my great great grandparents. I know they had 1 son, named Andrew Ostafin, who was married to a Paulina Ostafin(Swider), they immigrated to the US. Andrew was born in 1856. I also know Andrew had several sisters as well, but I don't know their names, I believe one sisters name was the same as the mother, Katarzyna, who also came to US in the very early 1900's.
