Looking for hometown of Moldau along the Moldau River (now Vltava River)circa 1877. Believe my ancestors are from this area. They would be Roble and Artz and perhaps the Roble name had a name change upon arrival in America. Supposedly came to New York in 1889 and settled in Latrobe, Pennsylvania. The name of the town Moldau has probably changed but I'm interested as to where it was on a map.
