Brinsmead, William a Congregational minister, was a native of Dorchester, Massachusetts. He entered Harvard College in 1646, but left in 1647, without taking his degree. He first preached at Plymouth, but he was laboring at Marlborough as early as 1660, though he was not installed there until October 3, 1666. As he was preaching on March 20, 1676, the assembly was surprised by the approach of Indians. All reached the fort safely except one man, who was wounded. The meeting-house and many dwellings were burned. Brinsmead died July 3, 1701. See Sprague, Annals of the Amer. Pulpit, 1:256.
