The surname McPhearson is of Scottish origin and dates back to the 16th century. It is believed to have originated in the Highlands region of Scotland, specifically in the areas around Loch Lomond and Loch Fyne. The name is thought to be derived from the Gaelic words "mac" meaning "son of" and "pearson" or "phearsain," which may have been an occupational surname referring to a person who worked with pearls or a personal name derived from the French "Piers" or "Pierre."
One of the earliest recorded instances of the name can be found in the Parish Records of Dunoon, Argyll, Scotland, in 1567, where a John McPhearson is mentioned. Another early reference is in the Regality of Dunfermline Court Books from 1586, which lists a Malcolm McPhearson.
In the 17th century, the name appears in the Exchequer Rolls of Scotland, where a Robert McPhearson is recorded as a tenant farmer in Arrochar, Dunbartonshire, in 1628. The Hearth Tax Rolls of 1691 also mention a James McPhearson in the Parish of Kilmodan, Argyll.
One notable bearer of the name was Sir John McPhearson (1633-1701), a Scottish soldier and landowner who served as the Governor of Dunottar Castle during the Wars of the Three Kingdoms. He played a significant role in protecting the Honours of Scotland (the Scottish Crown Jewels) from Oliver Cromwell's forces.
Another prominent figure with the surname was Reverend William McPhearson (1756-1829), a Scottish minister and author who served as the Moderator of the General Assembly of the Church of Scotland in 1820. He was known for his writings on church history and theology.
In the 19th century, the name spread to other parts of the British Isles and beyond, with individuals like James McPhearson (1823-1892), a Scottish-born businessman and philanthropist who made his fortune in Australia and became a prominent figure in the city of Melbourne.
Other noteworthy individuals with the surname include Alexander McPhearson (1870-1946), a Scottish-born Canadian politician who served as a member of the Legislative Assembly of Saskatchewan, and Katharine McPherson (1894-1976), an American playwright and screenwriter who co-wrote the Academy Award-winning film "The Informer" in 1935.
