Selestyne is in Origin.

Selestyne is a rare English variant of Celestine, ultimately from Latin Caelestinus (from caelestis, “heavenly” or “of the sky”). The shift from soft c to s reflects pronunciation in English and French, and the y inserts a modern, ornamental touch. The name’s roots connect to several early saints and popes named Celestine, lending it a quietly venerable aura, while 19th‑century France popularized feminine Célestine in literature and society.

Usage today is uncommon but recognizable through its classical base; Selestyne reads chiefly feminine in English, though the Celestine line has unisex precedent. Close variants include Celestine/Célestine (f.), Celestina (f.), Celeste (f.), Celestia (f.), Celestino (m.), and Célestin/Celestin (m.), with Selestine and Selestina as near‑spellings. Nicknames range from Essie and Lessie to Tina and Cece. The enduring meaning centers on the celestial - evoking sky, stars, and a serene, lofty quality.
