The history of the last name Kenehan

The surname Kenehan is believed to have originated in Ireland, with roots dating back to the 16th century. It is thought to be derived from the Irish Gaelic name "O Cianain," which means "descendant of Cianan." The name Cianan itself is a variant of the name "Cionaodh," which means "enduring" or "perpetual."

Kenehan is a anglicized form of the original Irish name, reflecting the linguistic and cultural changes that occurred during the English conquest and colonization of Ireland. The earliest known records of the name Kenehan appear in parish records from County Mayo and County Sligo in the late 16th and early 17th centuries.

One notable early reference to the name Kenehan can be found in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the early 17th century. The chronicle mentions a "Teige O'Kenehan" who was a prominent figure in County Mayo during the 16th century.

In the 18th and 19th centuries, the Kenehan name became more widespread in Ireland, particularly in the counties of Mayo, Sligo, and Galway. Several notable individuals bearing the name emerged during this period, including:

  3. Bridget Kenehan (1792-1875), a renowned lacemaker from County Mayo whose intricate lace designs were highly sought after.

As the Irish diaspora spread throughout the world, the Kenehan name traveled with emigrant families. In the late 19th and early 20th centuries, Kenehans could be found in various parts of the United States, Canada, Australia, and other countries with significant Irish populations.

Two notable individuals with the Kenehan surname from this period include:
