Chelor's exact birthdate is unknown; however, he is thought to have been born in about 1720.^[11][8] He was owned by Nicholson as early as 1736. In 1741, Chelor was admitted to the Congregational Church in Wrentham Center when he was supposedly 21. Chelor would become a freeman when Nicholson died in 1753.^[12][13] Along with freedom, Nicholson willed Chelor a workshop, 10 acres of land, tools and materials to continue independently. Chelor was married to Juda Russell in 1758, with whom he had shared eight^[a] children. In 1784, Chelor died without a will with an estate inventory valued at 77 pounds 2 shillings.^{[15][16][11][1]}
