John settled in Cambridge on the homestead deeded to him by his father, November 30, 1668. He also was involved in the trial of his family for calling the Holmans witches, and had to acknowledge his error in court or pay a fine. He took the cheaper course. He was a soldier in King Philip's war under Captain Thomas Prentice. He was in the Swanzey fight, June 28, 1675, and was in the Mt. Hope expedition later. He was also in Lieutenant Edward Oake's troop scouting near Marlborough, March 24, 1675-76, and in Captain Daniel Henchman's company, September 23, 1676, which marched to Hadley in early summer time. He was possibly the John Gibson in Captain Joshua Scottow's company at Black Point, near Salem, Maine, September, 1677, where the garrison was captured the following month by the Indians. He was admitted a
freeman, October 11, 1670, and held a number of minor offices. He married, December 9, 1668, Rebecca Harrington, born in Cambridge, daughter of Abraham and Rebecca (Cutler) Harrington, or Errington, as it was spelled and perhaps pronounced. John died October 15, 1679, of small-pox.
