The surname Gillespy is of Scottish origin, derived from the Gaelic personal name "Gille Easbaig," meaning "the servant of the bishop." This name was commonly given to those who worked in service to a bishop or within the church during the medieval period in Scotland.
The name is believed to have originated in the Highlands of Scotland, particularly in the areas of Argyll, Inverness-shire, and Perthshire, where the name was prevalent in the 12th and 13th centuries. Early records show various spellings such as Gillespie, Gillespy, Gillespie, and Gillespy.
One of the earliest recorded instances of the name can be found in the Exchequer Rolls of Scotland, which date back to the 13th century. In these records, a certain "Gillespie MacNachtan" is mentioned as a landowner in Argyll in the year 1264.
The Gillespy name also appears in the Ragman Rolls, a collection of documents recording the nobles and landowners who swore fealty to King Edward I of England in the late 13th century. Among those listed is a "Gilbert Gillespie" from Ayrshire, Scotland.
In the 14th century, a notable bearer of the name was Sir John Gillespie, a Scottish knight who fought alongside King Robert the Bruce during the Wars of Scottish Independence. Sir John Gillespie played a significant role in the Battle of Bannockburn in 1314, where the Scottish forces defeated the English army.
Another prominent figure with this surname was James Gillespie (1645-1723), a Scottish merchant and philanthropist who founded Gillespie's Hospital, a school for the education of poor children in Edinburgh.
In the realm of literature, one of the most famous bearers of the Gillespy name was James Gillespie Smyth (1737-1806), a Scottish minister and philosopher who wrote extensively on moral philosophy and ethics.
Other notable individuals with the Gillespy surname include Sir Robert Gillespie (1766-1814), a British Army officer who served in the Napoleonic Wars, and Eliza Maria Gillespie (1824-1888), a Scottish-born writer and journalist who wrote extensively about her travels in South America.
Throughout its history, the Gillespy name has maintained a strong connection to its Scottish roots, with many bearers of the name tracing their ancestry back to the Highlands and the ancient Gaelic tradition.
