Kerrin
Feminine
Kerrin is overwhelmingly a girls’ name — 1,004 girls against 10 boys since 1880.
County Kerry is named after a people rather than a place. Ciarraí means the people of Ciar, a legendary ancestor whose own name means dark — and Irish territorial names work that way generally: the land is named for who lives on it, not the other way round.

The story of Kerrin
The Irish habit of naming land after people runs through the whole map. Kerry is the people of Ciar; Connacht is the people of Conn; Ulster and Leinster carry tribal names with a Norse ending stuck on. The English convention is the reverse — you take your name from where you live, which is why English surnames are full of villages. Two neighboring naming systems, running in opposite directions, and the collision is visible on any map of Ireland where an English administrative name sits on top of an Irish tribal one.
Meaningnot established
Not established
Three routes are open. The name may be Karen respelled, which is a Danish form of Katherine; it may be built on Kerry, the county or the surname; or it may be a feminine of Kieran. All three were live options in the 1950s and none can be shown. The doubled r is the only distinctive thing about the spelling and it does not settle anything.

Fashion outlook
Kerrin 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.
