Cro-Magnon
The name "Cro-Magnon" was created by Louis Lartet, who discovered the first Cro-Magnon skull in southwestern France in 1868.  He called the place where he found the skull Abri de Cro-Magnon.  Abri means "rock shelter" in French; cro means "hole" in the Occitan language; and "Magnon" was the name of the person who owned the land where Lartet found the skull.  Basically, Cro-Magnon means "hole on Magnon's land."
