From the experts:
A name that seems to hail from the old Irish neighborhoods of Boston and New York, Terence actually dates back a lot further, to the time of a famous second-century poet, who started life as a North African slave in the house of a Roman senator and it was also borne by several early saints.
Out of style for several years -- possibly because of the feminization of nickname Terry -- Terence might be due for a comeback, much like his Irish crony Patrick. Spellings Terrance and Terrence now outperform the original. Off the list for a decade, Terence reached as high as Number 241 in the 1960s.
Actor Steve McQueen was born Terence Steven McQueen and Terence is also the birth certificate name of Monty Python's Terry Gilliam and Terry Jones.
