I have been recently researching my family tree for my grandson. My great grandmother was Bertha Niebuhr, b. 1864 in Hanover. They apparantly immigrated to St. Louis MO and became citizens about 1866. The 1870 census shows the family as Henry (b. abt 1837 in Prussia), Augusta (b. abt. 1843 in Hanover) and a baby Mina b. 1870. The 1880 census shows this family with a son, William F. b. 1874 or 1875. Henry disappears, but Augusta is in a later census listed with an even younger daughter Albertina. I have come up against a brick wall with this family. If anyone thinks they may have any useful information, please contact me.
