Hello, I have looked over this board a lot and don't believe I am related to anyone here, but I'm hoping some of y'all can help me. My ggg grandfather was Frederick William Alpert born on 12-29-1836 in Hamburg, Germany and married to Dorothea Kuhurt. They immigrated and settled in ND in 1884 and had several sons and daughters (I don't know the name of them all but there was an Otto, Ewald, Leopold and Emilie). Otto is my gg grandfather and was born on 6-5-1868 and married Magdalena Lippert.
My problem is I have hit a complete brick wall from when my family immigrated! I'm pretty sure they changed their surname, but I don't know what it was before. I also need to know of any good German genealogy sites I can search that are in English
