The Tenny/Olsav Family

I have been researching the Tenny Family, which came to America in 1638 from Rowley, Yorkshire, England. The earliest ancestor we have been able to trace is John Tenney, who was born in about 1539 in Brigham, Yorkshire, England.

My husband's family comes from Poland and Slovakia. It has been very difficult to find information on his side of the family. The earliest ancestor I have found is John who I think was been born in Czechoslovakia in 1905 and immigrated with his mother, Mary in 1906. Mary was born in Czechoslovakia in 1885. In Pennsylvania, she married Michael Olsav, who was born in Czechoslovakia in 1875. I have not been able to find out who John's father in Czechoslovakia was, or anything else about the family. Any information would be greatly appreciated!
