“Joseph Hill, brother of John Hill, who had served on this court briefly from 1711 to his death in 1713, was from Wells. Hill, like so many of his colleagues, was active in military affairs during these times. He first came on the court in April 1722. Though he was over fifty years of age in 1725, he had had less service in civil affairs than the other justices. John and Joseph Hill’s father, Roger, had been an early settler of Saco. Indian troubles, probably, account for John’s removal to Kittery and Joseph’s to Wells after 1700. Joseph Hill, like his fellow townsman, John Wheelwright, had a special interest in two of those who were to come before the court this day. Daniel Morrison and Malachi Edwards had been charged by the two Wells justices with disrupting the town meeting in that place two months before, and that disruption had included, on Edwards’s part, open defiance of orders given by the magistrates.”
