This given name means “from the ships island”. The name could be derived from an English given name “Ceolsige”, meaning "ship's victory", which could be an Old English (Anglo-Saxon) place name meaning "Cenel's island". Cenel's Island is a combination of the Old English (Anglo-Saxon) word "cenel", meaning "fierce" plus "eg", meaning “island”. The name Kelsey could have Scandinavian origins. The meaning seems to be "Isle of the ships." The origin of this name is still today quite uncertain.
