Finnian is a fair jig of a name, energetic and easy on the ear. Finnian (and brother Finian) is also familiar in its alternate spelling through the classic 1968 Broadway musical Finian's Rainbow, later made into a film starring Fred Astaire as Finian McLonergan.

Cohen is a common last name among Jews and an important spiritual name in the Jewish religion, associated with the hereditary priests who claimed descent from the biblical Aaron.

Like many short forms now popular as full names in the Netherlands, Coen—also spelled Koen—originated as the diminutive of the more old-fashioned Coenraad, the Dutch Conrad. In this case, it would be pronounced as KOON, with a short oo sound.
Alternatively, it may be used in the US as a variation of Cohen, which stems from the Jewish surname designating a priest, and thus pronounced as CO-uhn. Additionally, it may also relate to the Irish surname McCown ("of Connacht") or to the Australian place name, Coen, meaning "thunder" from its Indigenous roots.

Callen is a unisex Gaelic name growing in popularity here. Its newfound trendiness is possibly related to the Chris O'Donnell character on "NCIS: Los Angeles", known only as G. Callen. Jazz musician Cal Tjader's full name is Callen.

Brenner is an occupational surname for both a charcoal burner and a distiller of spirits. One of the least used of occupational surnames, it has that 'er' ending that definitely adds to its stylishness; a possible successor to Brendan.
