Keighan is a unique and distinctive given name of Irish origin. It is derived from the ancient Irish surname "Ó Caoimhín", which means "descendant of Caoimhín". The name Caoimhín itself comes from the Irish word "caomh" meaning "gentle", and the suffix "-ín" which denotes a diminutive or familiar form.
The name Keighan is believed to have emerged as a given name in its own right during the late Middle Ages, although it was still more commonly used as a surname at that time. Over the centuries, Keighan has been anglicized and adapted into various spellings, such as Keeghan, Kegan, Keagan, and others.
Keighan is not particularly associated with any specific historical figures or legendary characters. However, it has been used by several notable individuals throughout history, including the Irish poet and playwright, Sean O'Casey (1880-1964), whose real name was JohnFrancis O'Cathain, which is an Irish variant of Keighan.
Today, Keighan is still a relatively uncommon given name, but it continues to be chosen by parents who appreciate its unique sound and Irish heritage. It has also gained some popularity in recent years due to its use in popular culture, such as the television series "Pretty Little Liars" which featured a character named Keegan Dark. Despite its modern usage, Keighan remains deeply rooted in its ancient Irish origins, carrying with it the gentle spirit of its ancestor Caoimhín.
"The name Keighan has seen a steady increase in popularity over the years, with its peak occurring in 2014 and 2016, and a slight dip in recent years."
