The surname McKeller originated in Scotland during the medieval period. It is a variant of the Scottish surname MacKellar, which is derived from the Gaelic personal name "Ceallach," meaning "bright" or "bright-headed." The name likely referred to an ancestor with light-colored hair or a bright complexion.
The McKellers were traditionally found in the regions of Argyll and the Hebrides, where the name first appeared in historical records. One of the earliest recorded mentions of the name was in the Exchequer Rolls of Scotland in 1326, which referred to a person named "Gillecrist MacKellar."
In the 16th century, the McKeller family held lands in the Isle of Bute, and they were among the principal families of the region. In 1592, a person named John McKeller was recorded as the proprietor of the lands of Glencalvie in Bute.
The McKeller name has been associated with several notable figures throughout history. In the 17th century, John McKeller (1622-1688) was a Scottish theologian and minister who served as the Principal of the University of Glasgow.
Another prominent McKeller was Donald McKeller (1770-1854), a Scottish merchant and landowner who owned extensive properties in the West Indies and Scotland. He was known for his philanthropic work and support of education.
In the 19th century, James McKeller (1810-1879) was a Scottish inventor and engineer who developed several innovations in the field of iron manufacturing. He held patents for improved iron-making processes and contributed significantly to the industry's development.
