The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Jack
God is gracious
The meaning belongs to John, from the Hebrew Yohanan. Jack is John plus the diminutive -kin, worn down over four centuries of use. The persistent claim that it comes from the French Jacques does not survive the medieval record, where Jankin and Jackin are both plentiful and neither is used for a Jacques.
Yohanan → John → Jankin → Jack
How it traveled
By the later Middle Ages John was so common in England that a name for it was needed as a common noun, and Jack became that noun: a jack is a device that does a man's lifting, a jack of all trades does any man's work, a lumberjack and a steeplejack are men defined by a job, and the jack in a deck of cards was the knave — a servant. Very few names have been that thoroughly absorbed into a language.
James
From Hebrew Ya'aqov (Jacob) — either "heel" or "holder of the heel/supplanter", or "may God protect"
The Book of Genesis links Jacob to the Hebrew word for heel, since he was born grasping his brother Esau's heel, which gave the traditional reading "supplanter". Semitic scholars instead reconstruct an original Ya'aqov-El, "may God protect". Both readings are seriously held; neither has pushed the other out.
Ya'aqov → Iakobos → Iacomus → James
How it traveled
James and Jacob are, at root, the same name. Hebrew Ya'aqov was written Iakobos by the Greek translators of the Hebrew Bible and the New Testament writers, and Iacobus in Latin.

Out loud, and in short
Jack
JAK
One syllable, four letters, and there is nothing to get wrong in any English-speaking country.
- Jackie — The warm extension, fully unisex in American use and strongly associated with particular twentieth-century figures.
- John — The full name behind it, available at any point without a legal change; it gives a formal option the short form lacks.
- Jacko — A British and Australian extension; informal, cheerful, and rare in American use.
James
JAYMZ
One syllable everywhere in English. The related forms elsewhere sound quite different — Jacques is ZHAHK, Séamus is SHAY-mus, Santiago is san-tee-AH-go.
- Jim — The standard informal short form for generations; also given on its own, though far less often than as a nickname.
- Jamie — Used for children and adults alike, and independently established as a given name for both boys and girls in English-speaking countries.
- Jimmy — Affectionate form, widely used in childhood and kept into adulthood by many; strongly represented among older generations.
- Jay — Initial-based short form, informal, and a standalone name in its own right.
- Also Jem.

The trade-offs, name by name
Jack
Strengths
- It is as short and unambiguous as a name gets, and everyone in the language knows it.
- John sits behind it as a formal option with no paperwork required.
- It has been in continuous use for seven hundred years and has never sounded dated.
To consider
- It is currently very well used and climbing, so a boy will meet others of his age.
- It doubles as a common noun and a verb in several senses, so the puns are constant and old.
- Nearly every child given this spelling is a boy; the record's girls are very few.
James
Strengths
- Spelled one way and known one way across the entire English-speaking world; almost never misheard or misspelled.
- A deep bench of short forms already in use — Jim, Jimmy, Jamie, Jay — so a boy can choose his own register later.
- Charts in Canada, Scotland, and England & Wales as well as the US, so it crosses borders without translation.
To consider
- It is one of the most heavily used boys' names in American history, so a James will meet other Jameses — in his classroom, on his team, at work.
- Because so many bearers are now in their later years, Jim and Jimmy read as belonging to older generations; the full James and Jamie sit more neutrally.
- It has become a default middle name for many families, which some parents feel makes it less of a statement in the first slot.
