Shailie belongs to the busy modern Shay/Shayley/Shaylee family. Somewhere far upstream stands Irish Seaghdha, an old name variously read as 'hawk-like' or 'admirable', but no documented line runs from it to this spelling. Shailie reads instead as a fresh American coinage, and its routes are uncertain, which we note (said 'SHAY-lee').
It appears only rarely for girls in the U.S. Rare, breezy, and modern.
Did you know? The Shay- family reaches back toward Irish Seaghdha, an old name sometimes glossed 'hawk-like'. Shailie is a modern respelling far downstream of that, and its own route is uncertain, which we note.
