Meaning and origin of Kennedy
Kennedy is an Irish name that is usually said to mean “descendant of Cinneide”.
Kennedy comes from the Irish surname O Cinneide, meaning descendant of Cinneide. That personal name is usually explained as combining ceann, head, with a second element often read as armored or helmeted, although misshapen head is another traditional reading. The O Kennedy family was historically rooted in north Tipperary. As a first name it took off in the United States after President John F. Kennedy, and it has since become a popular choice for girls. It is bright and rhythmic. Kenny and Kenna are possible nicknames.
