My great great grandmother Bertha Sophie Helfrich b. 4/5/1870, came over to the US from Freiberg, Baden Germany sometime in the 1880s. Her nephew, Erich Hafner b. 6/11/1905, immigrated to St. Louis, MO from the same area and became a US citizen in 1923.
I have no other information about this family, other than Bertha's death records, Erich's immigration manifest saying that his aunt (Bertha) was sponsoring him, and Erich's Declaration of Intention.I am assuming that Erich's mother was Bertha's sister, based on the difference in the surname, but I have hit a brick wall.Can anyone help me?Thank you!
