James Halsy II (1695-1767), a mathematical instrument maker, was born in Boston on April 10, 1695, the son of Nathaniel and Hannah (Gross) Halsie. The parents had been married by the Reverend Cotton Mather in June 1693.[87] In 1716 young James Halsy was a member of the Artillery Company, and by 1720 he had the rating of 4th sergeant. He held town offices and was one of the founders of the New Brick Church of Boston. On May 30, 1717, he married Anna Gutridge (Goodrich). Ten years later, on September 22, 1727, he bought a house and land on North Bennett and Tileston Streets from Hugh Hall, a merchant; at the same time he deeded to Hall some land and a house adjacent to the latter on the southwest side of Green Street. On January 5, 1837, he deeded to his aunt(?), a single woman named Huldah Gross, a house and land on Ann Street that he had inherited from Thomas Gross, his grandfather. Several more real estate negotiations were recorded in the course of the next few years. In October 1740 he purchased a house and land on the north side of North Bennet Street from John Endicott; in January 1741 land on the east side of North Bennett Street; and in November 1748 half of the house and land of Edward Pell, adjacent to Huldah Gross, on Cross Street; finally, in October 1753, he purchased land on Tileston and North Bennett Streets from John Grant.[88] Halsy died on January 2, 1767, at the age of 72. In his will dated May 1, 1766, and probated January 2, 1767, by which his wife Anna was the executrix of his estate, he left her the income of his real and personal estate. He apparently was survived by three daughters and a son, also named James Halsy. He divided his real estate in Boston amongst his daughters, and to his son he left land in New Hampshire.[89] The only known surviving instrument bearing James Halsy's name is a wooden surveying compass (fig. 41) in the collection of the Peabody Museum in Salem. The engraved compass card is quite similar to the one used by Thomas Greenough. In the central medallion is an elaborate royal crown, and in the circle around the medallion is inscribed "Made and Sold by JAMES HALSY near Ye Draw Bridge in Boston."[90] [Illustration: Figure 41.--Wooden surveying compass made by James Halsy (1695-1767) of Boston.

His father was a shipwright in the North End of Boston, and one of Thomas's brothers, Newman Greenough, became a sailmaker. Thomas also had a sister named Jerusha, who later figured in his real estate negotiations.
