The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Alonzo
From Germanic roots usually read as "noble and ready"
The second element, funs ("eager, ready"), is agreed on. The first is not: most read it as adal, "noble," giving "noble and ready"; others trace it to hadu or hild, both meaning "battle," which would make it something nearer "ready for battle." All three are genuine Germanic name-elements, and all three were in circulation among the Visigoths.
Adalfuns → Alfonso → Alonso → Alonzo
How it traveled
The name begins as a Germanic compound carried into Iberia by the Visigoths, and it stuck: Alfonso became one of the great royal names of medieval Spain and Portugal, worn by kings of Castile, León, Aragon and Asturias for centuries. Ordinary Spanish speech wore Alfonso down to Alonso, and Alonso is the form that spread widest — including to the hidalgo of La Mancha in Cervantes' novel.
Frank
a Frank; free
The Franks were the Germanic people who took over Gaul and gave France its name; their own tribal name may come from a word for a javelin, though that is argued. Under Frankish rule only Franks held full legal freedom, which is how francus in medieval Latin came to mean free, and English frank, franchise and enfranchise all descend from that. Frank as a personal name is a short form of Francis, which means the Frenchman.
Franci → Franciscus → Francis → Frank
How it traveled
Francis was a nickname before it was a name — a cloth merchant's son in Assisi called Francesco for his father's trade with France — and it became one of the great European names through him. Frank shortened it and then outgrew it: in America, Frank has been given far more often than Francis for well over a century, and a great many Franks were never christened anything longer.

Out loud, and in short
Alonzo
uh-LON-zoh
Stress on the middle syllable. Spanish speakers say ah-LON-so with a lighter first vowel and an s sound for the z; both are correct for their own language.
- Lonzo — The most common informal short form; also used on its own as a given name.
- Zo — Clipped to the last syllable, informal, common in sports and among friends.
- Lonnie — An older informal short form, and a standalone given name in its own right.
- Al — The plainest option, informal, shared with Albert, Alan and Alfred.
- Also Alo.
Frank
FRANK
FRANK, one syllable, rhyming with bank. German says Franz with a ts at the end; Italian Franco has two syllables. The English name is as plain as a syllable gets and has never been ambiguous.
- Frankie — The name softened, warm in nearly every setting and used for either child.
- Francis — The long form standing behind it, used on documents by some and by no means all.
- Franco — The Italian form used as a nickname, which travels well in Italian-American families.

The trade-offs, name by name
Alonzo
Strengths
- A documented line running from Visigothic Iberia through the medieval Spanish and Portuguese kings to the present — few names have a record that clear.
- Sits comfortably in English and Spanish alike, with close relatives in Italian, Portuguese, French and German.
- Ready-made short forms already in real use: Lonzo, Zo, Lonnie, Al.
To consider
- Alonzo and Alonso are both established spellings, so expect a lifetime of gentle corrections — the z version will get written with an s and vice versa.
- It is strongly represented among older generations, which means most people who know an Alonzo know a grown man rather than a child. That fades as any name comes back around, but it is true right now.
- A child with this name will most likely be the only one wherever he goes. That is a real pleasure for some families and a small burden for others — being the only one means always being the one who explains.
Frank
Strengths
- One syllable, five letters, understood instantly everywhere English is spoken.
- The etymology is genuinely remarkable and connects the name to a whole family of English words.
- Frankie is available and works for either child.
To consider
- It is very strongly represented among older generations and reads that way to many people.
- The word frank is also an adjective meaning blunt, which gets played on regularly.
- It reads as a short form to some people even though it has been independent for a century.
