About 1 girl in 4,871 born in 2025 was given one of these spellings — against 1 in 44,646 for Luiza 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 Davette test

Luiza's later chapters haven't been written yet, so we borrowed them: Davette climbed just as high around 1968, and its whole arc is on record. Line the two peaks up, and Davette's path sketches the road Luiza is walking now.
