The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Florence
flowering
The Latin name of the city means flowering or prosperous, and the reading is not in dispute. The personal name comes from the city rather than from the adjective directly, which is a distinction worth keeping: it is a place name used as a name, in the nineteenth-century manner, rather than a virtue or a description applied to a child.
The Latin name of an Italian city → Taken as a personal name in the nineteenth century → Extremely common in America around nineteen hundred → A long absence and a return, in Britain first
How it traveled
She went to the Crimea, found that far more soldiers were dying of disease than of wounds, and came back determined to prove it to a government that did not want to hear it. Ordinary tables of figures were being ignored, so she developed a circular diagram in which each month is a wedge and the area of the wedge shows the deaths, colored to separate disease from injury, and the shape of the thing is impossible to misread: an enormous blue mass of preventable death dwarfing everything else.
Sunny
sunny — full of sunlight, bright with sun
The word is attested in English from around the fourteenth century, built on Old English *sunne*, 'sun'. Sunny also works as a short form of longer names — Sonia and Sonya, Susannah, the Norwegian Sunniva — and is widely used as an informal everyday name in India for men and women whose formal names are quite different.
sunne (Old English) → sunny (Middle English adjective) → Sunny
How it traveled
This is a vocabulary name: English took *sunne* from its Germanic roots, and by the Middle Ages had the adjective *sunny* for weather and, soon after, for people. For a long stretch it lived as a pet name rather than a legal one — the thing you called someone rather than the thing on their papers — which is the usual path for warm little words like this.
Where a reading is contested the note says so — this page does not turn a guess into a fact. The chain is each name's recorded forms, oldest first; the story is its opening, told in full on the name's own page.
Out loud, and in short
Florence
FLOR-unce
Two syllables, stress on the first, with the second reduced almost to nothing. French says the same spelling with the stress at the back and a nasal vowel, which makes it a noticeably different name.
- Flo — The shortest form, plain and older-sounding than the full name.
- Florrie — The affectionate Victorian form, which has come back in Britain ahead of the full name.
- Ren — Cut from the back, unisex and thoroughly modern in feel.
Sunny
SUN-ee
Stress on the first syllable, exactly like the weather word. It sounds identical to Sonny, which is where the spelling confusion comes from rather than from the pronunciation itself.
- Sunny — Already the short form: it serves as the everyday name for Sonia, Sonya, Susannah and Sunniva, and equally stands alone as a full given name.
- Sun — Informal clipping used within families rather than in writing.
- Sunnybear / Sunnyboo — Household-only extensions, of the kind short names attract from parents and grandparents.

The trade-offs, name by name
Florence
Strengths
- It is completely familiar, universally spellable and needs no explaining.
- Flo, Florrie and Ren are three very different registers from one certificate.
- It carries a real city and a genuinely formidable historical bearer.
To consider
- It was associated with a very distant generation for most of the twentieth century, and that association is only now fading.
- The revival is much further along in Britain than in America.
- The spelling is on the register for boys as well, which reflects an older Irish usage.
Sunny
Strengths
- Everyone can already spell and say it — it is a common English word, so it needs no correction at the pharmacy, the airline desk or a new classroom.
- Two syllables, open vowels, no consonant clusters: it travels easily into languages that struggle with English sounds.
- Recorded for both girls and boys, so it does not have to be reassigned or adapted.
To consider
- Sonny is the homophone, and a lifetime of gentle corrections comes with the territory — spoken introductions will not distinguish them, and written ones often guess wrong.
- Word names invite commentary. People will make the obvious joke about weather or mood, including on days when a child would rather not hear it.
- Most children given this spelling are girls, so a boy called Sunny will occasionally be assumed female on paper — easily handled, but worth knowing in advance.
