Keoghane

Keoghane is a surname of Irish origin. It is an anglicized form of the Gaelic Ó Cadhain, meaning "descendant of Cadhan." The personal name Cadhan itself is believed to derive from the word "cadh," meaning "geese," or possibly "cadhan," meaning "wild goose." The O'Cadhain clan was historically associated with the barony of Moycashel in County Westmeath, Ireland. Over time, as Irish names were anglicized, Ó Cadhain became Keane, Kean, and Keon, as well as Keoghane and variations thereof.

Individuals with the Keoghane surname can be found in Ireland and in countries with significant Irish diaspora, such as the United States, Canada, Australia, and the United Kingdom. Genealogical records indicate the presence of the Keoghane name in various regions of Ireland, with some concentration in Munster province. Like many Irish surnames, Keoghane has been carried by emigrants and their descendants who have contributed to the cultural and social fabric of their adopted homes. The surname's origins are rooted in ancient Gaelic heritage, reflecting a lineage tied to specific ancestral territories and clan structures within Ireland.
