MacGREGGOR, James, clergyman, born in Ireland in 1677; died in Londonderry, New Hampshire, 5 March, 1729. He received a thorough classical and theological education, and had charge of a Presbyterian church in the north of Ireland. The oppressions to which Presbyterians were at that time subjected induced him to emigrate with about 100 families. They landed at Boston on 14 October, 1718, and established near Haverhill the town of Londonderry, where they organized the first Presbyterian church in New England, of which he assumed the pastoral charge without the ceremony of instaliation.--His son, David, born in Ireland, 6 November, 1710; died in Londonderry, New Hampshire, 30 May, 1777, studied theology with his father's successor, and was ordained pastor of a new parish in the western part of Londonderry in 1737. He took an active part in the great awakening that began in 1741. In 1755 he declined a call to the Presbyterian church in New York city. His discourses include " Professors warned of their Danger" (Boston, 1741); "The Spirits of the Day Tried" (1742); and "The Believers all Secured" (1747).
