Served in King Philip’s War in 1676 under Capt. Samuel Wadsworth and Capt. John Holbrook. His daughter Sarah Mercy was a grantee in 1733 of Narraganset No. 4 for his service.

Will for James Hadlock, Sr of Salem at http://www.essexcountyma.org/wills/hadlockj.htm lists son James. This seems to be his uncle, as there are records of James consistantly at Salem. Jacobus theorizes that James(1) had a brother Nathaniel of Charlestown. Nathaniel’s widow married Roger Draper, who may have been a cousin of Sarah’s father James. Savage's completely confused the two: JAMES, Roxbury, m. 19 May 1669, Sarah Draper, had Sarah, b. 16 Dec. 1670, rem. to Salem, there had, in 1678, w. Rebecca, d. prob. of Richard Hutchinson, wh. he m. May 1658, unless the numerals in Essex Inst. II. 150 and 1, be wrong, as they prob. are; s. James, and John, ds. Mary, Hannah, there said to be b. July 1657; Sarah, Sept. 1659; and Rebecca. But possib. he had some of these by ano. w. for the will of Hutchinson, 1682, calls him s.-in-law, but names not the w. nor any Hadlock gr.ch. exc. Sarah. James, jr. was incl. in the tax list (Mr. Felt assures me) of 1682 for Salem vill.
