My gr-grandfather Heinrich/Henry Busch (b.1849), along with his two sons Carl/Charles (b. 1875) and Johann/John (b. 1877) and new wife Madglena Meidel Busch (age 19) immigrated to Pennsylvania in 1881 from Mulhausen, Prussia. I am trying to find out which Mulhausen he is from. There are about 17 Mulhausens in Germany plus the big one on the border in Alsace.
