There is some extent listing of the Elke Family Tree on Ancestry which was done by my uncle Marvin in the past year or two. If you Search Herman Elke (sr) you will find the info. Herman was the father of the Elkes who are burried at the Moravian Cemetary in Chaska and also my great grandpa. I have recently made some scans of the family that go back to the 1800's mn and previous from Josephine earlier. I think we traced herman to Berstadt GR (Prussia area) there is a ships transcript that comes up with Herman Oelke which is also a spelling or the original spelling of our name and there where others. I noticed the 1940s census and some of the elkes chose to list their birthplaces differently because it was not popular to be German during that time. If you are interested I am still working on the photos that I scanned...I live in Jordan, MN which is the town next to Chaska and there are many Elkes in the area..most my brothers and sisters or 1st cousins. I am still working on more history, just was side tracked lately feel free to contact me and I will do what I can.
