My relatives are: Anthony Valeko (1872-1941) and his wife Frances (1880-1965). I am having a difficult time finding immigration records for them and for their children: Mary Valeko (1905-1993); Joseph Valeko (1904-1933); Frank Valeko (1906-1960). I think that they came over around 1910, give or take a few years. Death certificates list them as having originated in Kreszow. They moved to Detroit and later to Otsego, Michigan.
Because of the Anglicized "Valeko," it is hard for me to search records. I have had no luck. Any suggestions?
