MY GGM was named Marie/ Mary Hrabak, born in Bohemia in 1848. Her parents were Wencl and Josephine. SHe had at least one brother John. By 1886 she was in Western PA, Fayette Co, near Connellsville/ Dunbar where she married my GGF Frank Cervenka. He was also from Bohemia, born in 1845. He died in a coal mining accident in the HC Frick mine in 1891, they had 3 children, James, Frank and Rose. Her bother lived nearby and had at least 2 children, John and Ella.
Is Josephine the mother of your ancestor Wencl? The time frame is about right for him to be a brother to Marie. I do not know what town my GGM came from in Bohemia. Would appreciate more info if you have any. Thanks
