NATHANIEL2 LYON [Peter1] was born in Dorchester, Mass., Dec. 28, 1654 (D); baptized Dec. 31, 1654 (D Chh.); died March 15, 1705 (D). Of Nathaniel also very little is known; and he also preferred fighting to weaving, for we find him in garrison at Springfield in 1676, during King Phillip's War.  He was in Dorchester in 1700; but had a lease of land in Canton from the Indians, and had 50 acres laid out to him by the proprietors on the road leading to Dry Pond.  His wife died March 27, 1705 (D.); and the Dorchester record, "Nathaniel, d. March 15, 1705," evidently refers to him. Children of Nathaniel Lyon:   *17.   I.   Nathaniel, b. 28, 10 mo., 1680; m. Nov. 27, 1707, Esther White; d. Sept. 5, 1718.   18.   II.   Zachariah,§ b. 26, 2 mo., 1691; m. May 21, 1729, Sarah Drake; d. June 22, 1749.   19.   III.   Mary;‡ d. Sept. 18, 1718 (D).   20.   IV.   Anna (Hannah), bp. 21, 3 mo., 1704 (D.Chh.). §Zachariah was baptized in Canton, June 3, 1721-2, and joined the Canton Chh. Jan. 10, 1722-3.  The baptismal date is somewhat unusual in the Dorchester family, though regular enough in Connecticut lines.  It is possible that Zachariah married about 1720, having a son Zachariah, baptized in 1721, and marrying Sarah Drake as a second wife.  There is nothing in the records, however, to show this.  The inventory of the estate of Zachariah of Stoughton gives £180 18s. 5d. left to his widow by will, and £304 18s. 5d. not disposed of.  His will, dated Jan. 20, 1749, proved Jan. 30, 1749, leaves all real estate and one-half his personal estate to his wife Sarah, who is named executrix.  As he did not dispose of the whole of his estate, his widow Sarah was appointed administratrix.  No heirs are named.  This Zachariah may have been of the fourth generation, and it may have been his widow, "Mrs. Sarah Lyon m. (int. April 20, 1759) Jonathan Jordan" (St.).  [Sarah Drake, daughter of Thomas and Sarah (Pool) Drake, was born Oct. 20, 1703.  She married 2d (int. Sept. 2, 1759) Benaiah Smith (Drake Fam.).] ‡Mary was severely injured in 1711, and "Dr. Boyleston sued the town of Boston to recover £31 for the care of Mary Lyon wounded on the road to Boston."  The accident probably hastened her death.
