Kinsley

From a surname that was derived from an English place name, itself meaning "clearing belonging to Cyne". The Old English given name Cyne is a short form of longer names beginning with cyne meaning "royal".

As an American name for girls, Kinsley was very rare before 1990. It has steadily grown in popularity since then, perhaps inspired by similar-sounding names such as Kinsey and Ainsley (both of which it has surpassed).
