Our story of Robby

Ours, offered as ours. Robert produced an unusual number of English pet forms because medieval English made nicknames by rhyming: Rob gave Hob and Dob and Nob, all of which became surnames — Hobson, Dobson, Robinson. Robin was a diminutive of it before it was a bird's name, and the bird was renamed after the man. Robby is the modern American form of a name that has been generating variants for nine hundred years.

counting every spelling

The SSA counts spellings, not names. Robby went to 22 boys in 2025, but Roby is the same name said out loud. Together the 2 spellings went to 29, which makes it the 899th most-given boys’ name of the year — 3,640 places above the chart.

About 1 boy in 58,899 born in 2025 was given one of these spellings — against 1 in 77,640 for Robby itself.

Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method

The Casimir test

Every popular name lives one long story — a climb, a peak, a slow settling back. Robby's later chapters haven't been written yet, so we borrowed them: Casimir climbed just as high around 1917, and its whole arc is on record. Line the two peaks up, and Casimir's path sketches the road Robby is walking now.
