Can someone help me find some immigration and marriage details? The person in question is John George Gerlach. According to the 1900 census, he was married in 1884 to Wilhelimina Augusta “Minnie” Jahn and immigrated from Germany in 1864. He was born in Feb 1858 in Saxony, Germany and died March 31, 1928 in Cambridge, Dorchester, Maryland. Ancestry says his parents are Franz Gerlach and Auguste Schmidt, but I cannot find any evidence to support that so far.
