Looking for family of Michael Valiska, of Prince George County. Emigrated from Czechoslovakia in the late 1800's. He was born in Slovakland in 1874. His second wife's name was Susie. She had one child, Margaret Uhrin, by a previous marriage. Their children were Albert, Helen, Robert, Ethel, Rudolph, George and Olga, all born in VA. Any help would be greatly appreciated. Don't have much else to go on.
