You are a cousin. I descend from the older sister of William and John,namely Elizabeth Gertrude Schulmeyer. The Charles Keefer(Kiefer) you refer to in your post was the husband of Elizabeth Gertrude.I have this generation fairly well documented.My grandparents were from Indianapolis as was my mother.I was even born in "naptown" although I grew up west of the Mississippi.Bet you have Indiana connections.
I would love to exchange information and get this part of the family more documented. Sending this in case your email has expired.
