I am looking for information regarding my grandfather's sister, Mary/Maria MUSIAL/MUSCIAL (maiden name LANCASS, which was either shortened or changed to LANCE) and her ancestors. Mary was born in 1896 in New York City and is the mother to baseball star Stan MUSIAL; she later lived in Donora, PA and St. Louis, MO. Mary's father was John LANCASS/LANCE. Mary's mother's name was Sussana (Susan) HIFCO or PETERS (Mary's application for a social security card indicates HIFCO whereas her brother's indicates PETERS). Mary's siblings were Victoria, Anna, Adam, and James. Any information would be greatly appreciated!
