I believe my husband's family is related to your great grandmother Mary. If so, her last name is HRUSKA. My mother-in-law remembers her Great Aunt Mary(HRUSKA)marrying a VRABEL and having two daughters Anna and Mary. Anna married a KUCHMARIAK (spelling??) and had a daughter Ruth. Mary HRUSKA would have been born in the 1880's. Does this match your information? If so, I would love to exchange information.
