John Douglas (1636) bought Cold Spring Manor on May 10, 1677 from Josias Fendall for 22,000 pounds of tobacco. It consisted of a home on 1,050 acres on the west side of the Patuxent River in Mt. Calvert Hundred (now part of Patuxent Hundred) in Prince George's County, Maryland . The manor came with all rights of "Lord of the Manor."
500 acres was inherited by his John's son John Douglas (1664) who left it to his son, Benjamin Douglas (1685) who sold part in 1705. The residue of Cold Spring was inherited by John's younger sons, Joseph Douglas (1675) and Charles Douglas (1678).
