William Montague was an Anglican cleric at Old North Church in Boston and St. Paul's in Dedham, Massachusetts.
Montague was born in South Hadley, Massachusetts on September 23, 1757, to Joseph and Sarah Henry Montague. He was graduated from Dartmouth College in 1784.
He was married to Jane Little. Their daughter, also named Jane Little Montague, was a teacher at the Mill Village School and the First Middle School in Dedham. Another daughter, Sarah Ann Montague, taught in the East Street School. She had a son who served in the Civil War as a captain in the 38th Infantry Regiment.
While in England, Montague obtained the musket ball that killed Joseph Warren. His son, William Henry Montague, donated it to the New England Historic Genealogical Society, an organization he helped found. Montague also fought in the Revolutionary War.
He died in Dedham July 22, 1833.
He was ordained by Bishop Samuel Seabury of Connecticut. Montague was rector of Old North Church in Boston from 1787 to 1792. After traveling to London in 1790, he became the first minister ordained in America to occupy a pulpit of the English Church.
