Fairmont Park was established by the City of Philadelphia in 1812 as a public park. It lies astride the Schuylkill River on the outskirts of the city and contains among other attractions some eight Georgian Mansions.

Among these is Mount Pleasant described by John Adams, the Second President of the United States who dined there in 1775, as "the most elegant seat in Pennsylvania".

It was built in 1761 by John Macpherson out of a fortune he had made as a privateer captain. President Adams said he had a clever Scotch wife and that he had been nine times wounded in battle and had an arm twice shot off(!) He is believed to have been a native of Edinburgh and he claimed to be a nephew of Macpherson of Cluny.

Captain Macpherson married in 1772 in Campbeltown, his second wife Mary Ann McNeill, a great granddaughter of Lachlan McNeill Buidhe (1611-1695) of Tirfergus in Kintyre.

His first wife, Margaret Rodgers, died in 1770, leaving him with four children John, William, Margaret and Mary. John was born in 1754 and studied law in London before returning to Philadelphia. He was killed on 30th December 1775 while taking part in the disastrous attack on Quebec. William, after this event, obtained his release from the British Army and eventually became an Agrarian General. Margaret settled in Georgia with her husband John Berrien, where their son John Macpherson Berrien was born. He became a Senator and Attorney General for the U.S.A. in President Andrew Jackson's cabinet.

The house Mount Pleasant, which contains portraits of Captain Macpherson and the winsome Mary Ann, was sold to Benedict Arnold, who was, however, convicted of treason before he could occupy it with his bride, Peggy Shippen.

[ Added note from page 2 of Issue 26: "The book in the Mitchell Library" which contained the McKay genealogy quoted in the last number was obviously Collection Rebus Albanicis of which there is a copy in the Campbeltown Library. It contains a number of Highland Genealogies said to date from the 15th century.]
