BRUNSWICK – John Quincy Adams, an architect, conservationist and the direct descendant of two presidents, died April 30 from complications related to a broken hip. He was 95.

Adams, who went by Quincy, was the great-great-grandson of the country’s sixth president and the great-great-great-grandson of the second.

Adams lived most of his life on the family’s Lincoln, Mass., estate, where he raised horses. He was for many years the master of hounds at the Nashoba Valley Hunt in Pepperell, Mass.

He became a member of Lincoln’s Conservation Commission in 1960 when he made a persuasive argument to protect the town’s water supply by banning development in the area. He said in a 1978 interview that he hoped to stop rapid development in any way possible.

He set aside his family’s property as conservation land in the 1980s and moved to Maine in 1990.
