This name was used by Victor Hugo for the mother of Cosette in his novel 'Les Misérables' (1862).
From an Irish surname which was derived from Ó Fallamhain meaning "descendant of Fallamhan". It was popularized in the 1980s by a character on the soap opera 'Dynasty'.
From the English word fancy which means either "like, love, inclination" or "ornamental".
In modern French the word figaro has acquired the meaning "barber", reflecting the character's profession.
