The story of Lonzo
Alonso is the Castilian development of Alfonso, and both were royal names for centuries. English took Alonzo in the nineteenth century, when Spanish and Italian names had a vogue in American naming, and it was well used in the 1880s. Lonzo came off the back of it and appears in the records under its own name from the same period, particularly in the American South.
Meaning

From Germanic elements generally read as adal, noble, and funs, ready or eager; Alfonso and Alonso are the Spanish developments, and Alonzo the form that reached English. The clip takes the ending rather than the beginning.

- Lon and Lonnie are both complete short forms in their own right.
- Genuine nineteenth-century American use under its own name.
- Alonzo is the fuller name and will be assumed by many.
- It reads as a shortening to Spanish speakers, which may matter on a document.
- Five letters and two syllables is short, which some find slight for a formal name.
