The surname MCNIGHT is of Scottish origin and dates back to the 13th century. It is derived from the Gaelic words "mac" meaning "son of" and "naught" meaning "night." The name would have originally referred to someone who worked at night or had some association with night activities.
The earliest recorded spelling of the name is found in the Ragman Rolls of 1296, which were written records of Scottish landowners who swore allegiance to King Edward I of England. One entry lists a "Gillemichel McKnaght" from the county of Bute. This suggests the name was well-established in the western Scottish Highlands by that time.
In the 16th century, the MCNIGHT name appears in various parish registers and charters across Scotland. Notable examples include John McKnycht, a burgess of Glasgow in 1554, and Robert McKnicht, a landowner in Ayrshire in 1573. The spellings varied due to inconsistent record-keeping practices of the era.
One of the earliest recorded individuals with this surname was Sir Richard McKnight, a Scottish knight who fought alongside Robert the Bruce in the Wars of Scottish Independence in the early 14th century. He was rewarded with lands in Lanarkshire for his service.
Another figure of historical note was James McKnight (1591-1664), a Church of Scotland minister who served as Moderator of the General Assembly in 1649. He was a vocal opponent of the policies of King Charles I towards the Scottish church.
In the 17th century, the MCNIGHT name spread to Ulster during the Plantation of Ulster, when Scottish settlers were given land grants in the province of Ireland. This accounts for the surname's presence in parts of Northern Ireland today.
Archibald McKnight (1772-1839) was a prominent Scottish Covenanter minister who emigrated to America in 1792 and established several Presbyterian churches in Pennsylvania and Ohio.
Charles McKnight (1750-1792) was an Irish poet and playwright from County Monaghan, best known for his satirical works mocking the Anglo-Irish ascendancy class.
As the name originated in Scotland's western Highlands and Islands, place name connections may exist with locations like the Isle of Islay, where "McKnightstown" is a village name of possible MCNIGHT lineage.
