Cairns
A Scottish and Irish surname that likely comes from a word for a heap of stones or a cairn.
The #6,527 most common surname in the United States (2010 Census) — about 1 in every 59,466 Americans shares it.
Etymology
The name is generally linked to Gaelic words for a cairn, a heap of stones or a small rocky mound, and was probably first used as a descriptive topographic name. In the Irish tradition, the form is often connected with O'Cairn / Ó Ciaráin-type surnames in older scholarship, though the exact historical linkage is not always clear in 19th-century sources. In Scottish use, it is also associated with places marked by cairns or rocky hills, which fits the landscape-based explanation.
History
The surname is found in both Scotland and Ireland, and older writers sometimes treated Scottish and Irish forms together because the spellings overlapped. Lower and Barber both connect the name with a Gaelic word for a cairn or hill, while Woulfe lists Cairns among anglicized Irish surname forms. Modern bearers in English-speaking countries often descend from either Scottish or Irish lines, and the spelling has remained fairly stable.

Fun fact
The surname fits a very old landscape word: a cairn is the same kind of stone marker still seen on hills and in upland areas today.
