Genesee County info

Looking for any hints as to locating information on the Ephraim/Prudence Kendall family who lived in the Stafford area of Genesee County. Ephraim was buried in the Old Stafford cemetery in 1834.
We visited several years ago and have had no luck locating any info.
Anyone know of existing church or cemetery records?
We do know Prudence remarried before relocating the family to WI.
Any assistance is appreciated.
