Gender: M Origin of Thelonious: Latinized variation of German Tillman, “one who plows the earth”

One of the coolest of names, thanks to legendary jazz pianist Thelonious Sphere Monk, who inherited this Latin-sounding German name from his father. It has been used very sparingly since the 1960's, with just a sprinkling of baby boys receiving the name each year.

Monk's middle name Sphere is pretty unique too — a cousin of Cosmos and Cosmo.
