The story of Luiz
Clovis united the Franks and converted to Nicene Christianity rather than Arianism, which aligned his kingdom with Rome and shaped the church in western Europe. Eighteen French kings carried the name after him. Portuguese gives Luiz and Luís, and Brazil uses both heavily. It reaches American records with Brazilian and Portuguese families.

About 1 boy in 682 born in 2025 was given one of these spellings — against 1 in 61,003 for Luiz 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

What happens to a name after it peaks
The Anselmo test
Every popular name lives one long story — a climb, a peak, a slow settling back. Luiz's later chapters haven't been written yet, so we borrowed them: Anselmo climbed just as high around 1932, and its whole arc is on record. Line the two peaks up, and Anselmo's path sketches the road Luiz is walking now.
Luiz 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.
