origin

Medieval Welsh name of uncertain meaning.
Kim 1 f & m English
At the present it is usually considered a short form of Kimberly, but it in fact predates it as a given name. The author Rudyard Kipling used it for the title hero of his novel Kim (1901), though in this case it was short for Kimball. In her novel Show Boat (1926) Edna Ferber used it for a female character who was born on the Mississippi River and was named from the initials of the states Kentucky, Illinois and Mississippi. The name was popularized in America by the actresses Kim Hunter (1922-2002) and Kim Novak (1933-), both of whom assumed it as a stage name.
Kimball m English
From a surname that was derived from either the Welsh given name Cynbel or the Old English given name Cynebald.
Trahaearn m Medieval Welsh
