I would suggest that you contact Terry Kegebein. He lives in northern Indiana and might have information on the family members that moved into Illinois. My g grandfather moved up to Crystal Lake, Illinois sometime in the middle 1800's and purchased a farm in Crystal Lake. I know very little family history as my parents never talked about the family as I was a late comer and all the greats had passed away long ago. I remember an Edward Kegebein stopping by the house in 1961 for a visit. He lived somewhere in Indiana. I'm sure we are all related as there are so few Kegebeins listed in the phone books. The problem is trying to link everyone to a common heritage.
Send me an e-mail and I will send you Terry's e-mail address.
