I am looking for Edward C. Gamm 24 Aug 1844 in Germany, and came to America in 1865. He married Emily Huhnke in 1869 in NY City, NY. They lived in New Jersey and moved to South Stillwater, MN in the 1870's. They had 4 children that I am aware of. Charles 1871, Emma 1873, Gawond 1874, Edward 1878. They are listed on the 1885 census for Minnesota but then dropped off the census records and I cannot find out where they moved to. I would appreciate any help.
