John Adams Sr.

John Adams Sr. (February 8, 1691 – May 25, 1761), also known as Deacon John, was an English-American colonial farmer and minister. Adams was the father of the second U.S. president, John Adams Jr., and paternal grandfather of the sixth president, John Quincy Adams. He was the son of Joseph Adams Jr. (1654–1737), the grandson of Joseph Adams (1626–1694), and the great-grandson of Henry Adams, who emigrated from Braintree, Essex, in England to Massachusetts Bay Colony in about 1638. His other ancestors include John and Priscilla Alden. Adams worked as a farmer and cobbler (also called a cord-wainer or shoemaker) for most of his life.

Adams' descendants include many prominent persons in American history, and his home is a National Park, the Adams National Historical Park. Not only was he the father and grandfather of presidents; he also was a first cousin, once removed, of Samuel Adams. He died six years before his grandson John Quincy Adams was born.
