My great-grandfather, Alva Seybolt (1859-1943), was Paul Lee Seybolt's son (3rd of 4 children). Alva made extensive geneology records which were updated by his granddaughter Jean Seybolt Dufau. I have seen the grave sites of John Mickle Seybolt, wife Mary, John M. Seybolt, Jr.,wife Sarah, Paul Lee Seybolt, wife Antoinette (as well as many others) in the Plains Cemetery, Otisville NY. Paul Lee Seybolt's father, Lewis Arnold Seybolt (1797-1874) and his wife Phebe Clark (1799-1854), married 2/2/1820 are buried nearby in Manning Cemetery, Mountain Rd, north of Greenville.
