Rare spellings summarised here: Gilliam (157), Gillianne (38), Gyllian (29), Gillyan (16), Gilian (14), Gilly (6), Gillen (5), Gillan (5).
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.
