The history of the last name Keena

The surname Keena has its origins in Ireland, specifically in the western province of Connacht. It is believed to have derived from the Irish Gaelic word "caoine" which means "weeping" or "lamentation." The name likely emerged as a descriptive nickname for someone who was particularly sorrowful or prone to crying.

In ancient Irish records, the name was often spelled as "O'Caoine" or "O'Caoineadha," indicating its roots as a patrynomic surname. The prefix "O'" signified "descendant of" or "grandson of." This naming convention was common among Gaelic Irish clans and families.

One of the earliest recorded instances of the name can be found in the Annals of the Four Masters, a chronicle of medieval Irish history compiled in the 17th century. The annals mention a man named Fearghal O'Caoineadha who lived in the 13th century and was a notable scholar and poet.

The name Keena is also associated with various place names in Ireland, particularly in counties Mayo and Sligo. For example, the townland of Keenagh in County Sligo was once known as "Caoine" or "Caoinedha," reflecting the surname's local significance.

Notable historical figures with the surname Keena include:

  1. Toirdhealbhach O'Caoineadha (c. 1520 - c. 1600), an Irish poet and historian from County Mayo.
  2. Aodh O'Caoineadha (fl. 1650s), an Irish physician and writer from County Sligo.
  3. Eoghan Keena (1765 - 1828), an Irish rebel and participant in the Irish Rebellion of 1798.
  4. Michael Keena (1804 - 1889), an Irish-born American soldier who fought in the Mexican-American War and American Civil War.
  5. Patrick Keena (1834 - 1898), an Irish-American carpenter and union leader who played a significant role in the labor movement in New York City.

While the surname has evolved over time, with various spellings such as Keena, Keenaghan, and Keenan, its roots can be traced back to the ancient Irish clans and their tradition of descriptive and patrynomic surnames.
