Have found the obituary for Mary born Nov 10, 1820 in Tirol died Aug 26, 1905 in Glenmont, Ohio. Says she was one of 18(WOW!) children. Came to America in 1850 with husband, John Gruver (1816-1886), daughter, Mary Gruver (b.1849), her father, three brothers and a sister. Located in Pittsburgh, PA before moving to Shreve, Ohio by 1854. Not a clue how to find out her parentage or immigration information. Any help greatly appreciated.
