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 Jona test
Every popular name lives one long story — a climb, a peak, a slow settling back. Rein's later chapters haven't been written yet, so we borrowed them: Jona climbed just as high around 1925, and its whole arc is on record. Line the two peaks up, and Jona's path sketches the road Rein is walking now.
Rein sits in the calm middle of the cycle — neither chasing a wave nor sliding off one. Middle-of-the-cycle names age slowly and predictably.
