there is much info on here about some of that. Herman Elke is burried at the Moravian Cemetary in Chaska MN and there are records under google search. My uncle Marvin also started a family tree on here and that should contain the info you are looking for under Elke. My name is Dan Elke and I live in MN, I am researching more and have tons of photos of old pixs scaned from my uncle. I know he and his family came from MI to MN and settled in the Chaska Area, they are from the Prussia area of GR, Berstadt I think it was and there is a ship manefest listing my great grandma and grandpa going back to GR under the name Oelke which is how I believe it was originally spelled however there are also others I have found with same grand rels.
