30. William Sackett, 1691–1761, of Newtown, L. I., son of (7) Capt. Joseph and Elisabeth Betts Sackett, was married, in 1727, to Mrs Mary Janes. He died without issue. Much of his time and attention was given to agricultural pursuits. He, however, served several years in the magistracy. By his will he conveyed his homestead at Newtown to Dr. Jacob Ogden, and the residue of his estate, including several slaves, to his nephews, Samuel and John Moore, sons of his sister Anna and to Joseph Lawrence, the husband of his niece, Patience, the sister of said nephews. Dr. Ogden deeded to the church at Newtown the property willed to him by William Sackett. It had evidently, says Riker, been left to him in trust for that purpose. These premises now (1907) contain, with other buildings, the Episcopal parsonage house and new church.
