Sonny began as something people said rather than something they wrote down — an affectionate way of addressing a boy in English-speaking households, warm enough that it stuck to some men for life. It has been on the American books far longer than most nickname-names, and it is climbing again now, on both sides of the Atlantic. Two syllables, no hard consonants, and it lands the same way in Glasgow as in California.

The story of Sonny
English has used 'sonny' as a fond form of address to a young boy since the nineteenth century, and in American speech especially it became the household name of countless eldest sons who were never called anything else. From there it made the ordinary journey of a spoken nickname onto birth certificates, first as an informal second name and eventually on its own. In Italian-American families it also served as the everyday form of Santino and Salvatore, which is how it reached men whose legal names looked nothing like it. It is now recorded as a given name in its own right across the United States, England and Wales, and Scotland.
Meaning
'sonny' — an affectionate English term for a boy, from 'son'
The word traces back through English 'son' to Old English sunu. As a given name it comes from the pet-name use, not from any separate root.

The Darwin test
Every popular name lives one long story — a climb, a peak, a slow settling back. Sonny's later chapters haven't been written yet, so we borrowed them: Darwin climbed just as high around 1938, and its whole arc is on record. Line the two peaks up, and Darwin's path sketches the road Sonny is walking now.

The trade-off
- Short, two syllables, and pronounceable on sight for anyone who reads English — no correction needed at introductions.
- Already established as a given name in the US, England and Wales, and Scotland, so it travels without explanation across English-speaking countries.
- Long documented history in American usage, first as a household nickname and later as a registered name in its own right.
- Needs no shortening: it arrives already in its informal form, which suits both a small child and a grown man.
- Sunny is the homophone, and it is used for girls. Expect a lifetime of spelling it out over the phone, and of forms coming back with the wrong vowel.
- 'Sonny' is still a word — older speakers sometimes use it to address a boy or a younger man, occasionally with a note of condescension. Most people meeting a Sonny today will simply hear the name.
- There is no long formal version underneath it, so there's no fallback for contexts where someone wants a more official-looking first name. That matters less than it once did, though a longer middle name gives an easy option.
- It is rising, so a child named Sonny now may meet more of them growing up than the current picture suggests — still nothing like a classroom full.
