Cammie, yes there is a John and Lavina (Lovina) Klontz. They are buried at Silent Hill Cem, Stephenson County, IL. It appears the transcription of the stones reads as follows: John, (Co. D., 9?, IV I-must be somewhat unreadable), Jan 26, 1832-May 12, 1897. Lovina (wife) Mar 13, 1835-Oct 2, 1925. A son is buried on the lot also, Alvin Myno (son) 2 yrs.,10 m. 18 dys.
John was a brother to my ancestor William Klontz who remained in Greene Co., OH when the family moved on to IL.
