Irish Gaelic male and female name, derived from "raven".

Feichín is derived from the same source, and is consequently classed here as lesser synonyms.

Interesting Note: the 7^th century Irish Saint Fiachra settled in France and the "Hôtel St. Fiacra" in Paris was named in his honour. The French carriage "le fiacre" was given that name as they were well known to wait in front of that hotel.
