The story of Cassey
The spelling sits between Cassie and Casey, and the record settles which way it is read: nearly every Cassey is a girl. The doubled s pulls the eye toward Cassie, which nobody would mistake for anything but a girl's name, and the ending pulls it toward Casey, which has always leaned the other way; here the doubled s wins. Readers are apparently deciding on the first letters rather than the last two, and it is the sort of thing only a large record can show.

Fashion outlook
Cassey sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.
