I am searching for any information on Balthaser Knoebel born in Baden and married to Elizabeth Federer. He had at least on child, John B. (1846-1908). This son immigrated to the U.S. in 1868 and raised a family in Pittsburgh, Allegheny, PA. John's family included sons Oscar and John and daughters Elizabeth, Lena and Mary Theresa, my great grandmother (m Thomas Scanlon). Any insights or linkages would be appreciated.
