History of the Kennedy name

Kennedy is thought to derive from ceann eide, meaning 'helmeted head', an epithet given to an early ancestor. The main sept were a branch of the Dal gCais, closely related to the O'Briens, and were based in Tipperary, particularly around Ormond, where they remained a leading family into the modern era. From this base the name spread through Munster and, via extensive 18th and 19th-century emigration, became one of the best-known Irish surnames in America, most famously through the family of a Wexford emigrant whose descendants included a US president.
