I am John Schroeder's great granddaughter. My cousin has done extensive genealogy work on the Schroeder family and she asked me to visit the Frankfort Historical Society(I live in Frankfort). I got your name from a 1993 letter you wrote in their Karch file. I took pictures of the Frankfort graves and saw an old house on the property that the owner said was bought from the Heisner family who bought it in 1902.You can email me at mhainzinger@hotmail.com since I am not good at ancestry.com.
