More information

McAdam was born in Scotland. He was the youngest of ten children and second son of the Baron of Waterhead. The family name was traditionally McGregor, but was changed to McAdam (claiming descent from the Biblical Adam) for political reasons in James VI's reign. He moved to New York in 1770 and, as a merchant and prize agent during the American Revolution, made his fortune working at his uncle's counting house. He returned to Scotland in 1783 and purchased an estate at Sauchrie, Ayrshire.
