We publish a meaning only with a cited source and a confidence label, and never generate one. Meanings are being researched for the most common names first.
Wikidata records this spelling as a given name in Dutch, English, German and Swedish. That is where the name is used, not necessarily where it comes from.
Rare spellings summarised here: Louiza (100), Luissa (7).
Numbers are all-time US births. Links come from Wikidata’s “said to be the same as” (P460, CC0) and our spelling rule: at most two letters different, with the same sound pattern.
