McClarnon

McClarnon is a surname of Irish origin. It is an Anglicized form of the Gaelic name Mac Cláirnéin, meaning "son of Cláirnéin." Cláirnéin is a personal name derived from clár, meaning "board" or "flat surface," often referring to a plain or level area of land. The diminutive suffix -néin adds endearment or smallness to the name.

The McClarnon surname is primarily found in Ireland, particularly in the counties of Donegal and Tyrone. Emigration from Ireland, especially during the 19th century, led to the dispersal of the name to other countries, including the United States, Canada, and Australia.

Variants of the name include McClarnin and McLarnon.

Historically, families bearing the McClarnon surname were typically associated with farming and rural life in Ireland. As with many Irish surnames, tracing specific lineages can be challenging due to historical record-keeping practices. Genealogical research is often required to determine the specific origins and family history of individuals bearing the McClarnon surname.
