The surname Gemmel originated in Scotland and is a variant spelling of the name Gemmell, which itself is believed to be derived from the Old French word "gemel," meaning "twin" or "double." This suggests that the name may have been initially bestowed upon a pair of twins or someone who had a twin sibling.
The earliest known record of the Gemmel surname dates back to the 13th century in the Scottish county of Ayrshire. In 1296, a man named Robert Gemmyll is mentioned in the Ragman Rolls, a collection of homage rolls from Scottish nobles pledging allegiance to King Edward I of England.
Throughout the Middle Ages and into the Renaissance period, the Gemmel family held lands and estates in various parts of Scotland, particularly in the regions of Ayrshire, Renfrewshire, and Lanarkshire. The name can be found in several historical documents and records from that time, such as the Exchequer Rolls of Scotland and the Register of the Great Seal of Scotland.
One notable bearer of the Gemmel surname was John Gemmel, a Scottish merchant and burgess of Glasgow, who lived in the late 16th century. He was a prominent figure in the city's trade and civic affairs.
In the 17th century, the Gemmels were involved in the Covenanting movement, a Scottish Presbyterian movement that sought to protect the Church of Scotland from the interference of the English crown. Several members of the family, including James Gemmel and Robert Gemmel, were signatories of the National Covenant of 1638.
Another notable Gemmel was William Gemmel, a Scottish soldier and author who lived in the late 17th and early 18th centuries. He served in the Wars of the Grand Alliance and the War of the Spanish Succession and wrote a memoir titled "A Journey Through the Western Islands of Scotland" in 1707.
As the Gemmel surname spread beyond Scotland, it underwent various spelling variations, including Gemmell, Gemmill, and Gemmel. The name has been found in historical records throughout the British Isles and in areas where Scottish immigrants settled, such as North America and Australia.
