John and Mary Jane Corder are buried at Kossuth Cemetery, Mediapolis, Iowa
John 11 Oct 1841-9 Sep 1912
Mary Jane 25 Nov 1854-8 Nov 1927 wife

There is a Geneva Corder Nelson buried next to the above. She was born in 1886 and died in 1971. Don't know if she is their daughter or not, but I knew her descendants.

Did not find either of the other daughters you mentioned. There are lots of Klines in the Sperry area, many buried at Old Stone Cemetery, but I did not find a Charles there.
