About Alonzo
Alonzo is dashing and debonair, with a large measure of Latin flair.

Alonso Quijano was the real name of Don Quixote--Alonso being the Spanish version of the name. In the old Judy Garland musical Meet Me in St. Louis, Alonzo/Lon was the name of both her father and brother.
Horror film star Lon Chaney was christened Leonidas, but Lon Chaney, Jr. was Creighton at birth. Alonzo Mourning is a former basketball star who goes by the nickname Zo--much more modern sounding than Lon or Lonnie.
Alonzo is also given to girls.
