I am a distant relative of Erger family through my Great Aunt Mary Johana (Mayme) Schroer Erger( b. 1898 in Arcadia, IA). Mayme Schroer moved with her parents Rudolph and Katherine Leiting Schroer from Iowa to Brighton, Co in 1919. (my grandfather Bernard Schroer, b. 1888 in S.D., stayed in Iowa). Mayme married Peter John Erger April 28, 1920 in Brighton Co. They had eight children. Peter J. was the son of JOseph and Aloisa (Louisa) Zang Erger, born in St. Louis Missouri in 1896. Everything about the Schroer family I have came from either family sources not in Ancestry and/or finding information on Ancestry. The information about Peter J. Erger and his family came primarily from Ancestry. I haven't had much luck on FamilySearch or Rootsweb. I think I found a reference to Peter's oldest brother, Joseph C. on the internet It appears he may have been a Catholic priest assigned to St. Helena Church in Ft. Morgan Colorado between 1939 and 1952. Please contact me through my profile address if I can help you any further. Good luck with your search. It's so nice to find family.
