My wife's great grandmother was Mary Liska who married Anton Kraothcvil in New York on 12 Oct 1875. She was born 1854 in Kutna Hora Czech Republic.
I found on the 1870 Federal Census a Frank Liska born about 1830 in Austria and was living in New York. His wife name was Maria and they had the following children: Mary born about 1854; Amma born about 1856; Frank born about 1858; Barbara born about 1860; Joseph born about 1862 and Wenzalaus born about 1867 and a Joseph born about 1792 and he was a cigar maker. The story goes that the great grandmother worked also along with her sibbling makine Cigars.
