I am searching for information on my great-grandmother, Emilie, or Amelie, Erdmann; born Nov 12,1855 in Brandenburg, Prussia, near Berlin.She immigrated to US in 1867. July 9, 1876, she married Henry Heinsch in Ramsey Co., MN. They lived for a few years in Faribault, MN, but lived in St Paul from 1881 to her death in Mar 1932.She had a sister Wilhelmina Erdmann,(1836-1927) married to Theodore Rohland, who lived in St. Paul since the 1860's.She and Theodore and at least the first four of their children; Otto W., Frank J, Bertha, Anna, immigrated to the US in 1867. Did the Erdman parents come too?There is also a surviving brother named in Wilhelmina's obit. in 1927; August Erdmann of Clinton, WI.Anyone know of this Erdmann Family?
