Three Syllable Girl Names

There are two Abihails in the Old Testament, but her similarity to Abigail is probably responsible for its being so little known or used.

The Modern Greek form of Elpis. A lovely meaning with a sound reminiscent of vintage names like Elmira and Elvira, this name could nod to Greek heritage... or simply to hope.

Cirilla is the currently most-used version of this name, thanks to The Witcher series, but Sirilla is another spelling variant of the original Cyrilla, feminine of Cyril. Downside: that Siri nickname.

The three soft a's make for a calm and rhythmic name, though some risk of salami jokes.
