Need help finding the graves of Leonard and Esther Gallup

I need some help finding the graves of Leonard B. Gallup 1869-???? and his wife Esther (Plummer) Gallup 1869-Aug. 22, 1927. Leonards mother and father Lafayette and Adelia Gallup died in Unadilla twp. and are buried in Stockbridge. My family thinks that Leonard may have owned a farm on Kellogg Rd. in Oceola Twp at the time of his death. I contacted the Oceola Twp Clerk and she stated that they had no record of him in any of their cem. I also know that Leonards son, Lloyd is buried in Lakeview Cem. in Howell. I made contact there as well and was told that Lloyd his wife and two sons were the only ones there. Both Leonard and Esther are listed in the Livingston Co. Death Index. Leonard is Vol. 14 pg. 137 and Esther is Vol. 2 pg. 386 if that helps.
Any information would be of great help to me.
