What is the meaning of the name Cinneididh ?

Cinneididh is Irish, Scottish Gaelic in Origin.

Cinneididh is a Goidelic given name stemming from Old Irish Cennétig, built from ceann “head” + éide “armour, war-gear,” usually interpreted as “helmet‑headed” or “armoured head.” The exact second element is debated, but scholarly consensus favors the martial sense rather than the folk gloss “ugly head.” The name appears in early annals, most notably borne by Cennétig mac Lorcáin, 10th‑century Dál gCais ruler and father of Brian Boru.

In Ireland the name shifted from a personal name to a hereditary byname, producing the surname Ó Cinnéide, anglicized Kennedy; parallel development and adoption also occurred in Scotland. As a given name Cinneididh (Irish Cinnéide; Old Irish Cennétig; later Cinnéidigh/Cennetig; Scottish Gaelic Cinnèide/Cinneididh) is rare today, while Kennedy thrives as a modern unisex forename in the English‑speaking world. Historical use was primarily masculine.
