Physician. Imprisoned for giving aid to martyrs in prison, and while there converted the jailer by restoring sight to the jailer's daughter. While Valentine of Terni and Valentine of Rome sometimes have separate entries in martyrologies and biographies, most scholars believe they are the same person. There are several theories about the origin of Valentine's Day celebrations. Some believe the Romans had a mid-February custom where boys drew girls' names in honor of the sex and fertility goddess, Februata Juno; pastors "baptised" this holiday, like some others, by substituting the names of saints such as Valentine to suppress the practice. Others maintain that the custom of sending Valentines on 14 February stems from the belief that birds begin to pair on that date. By 1477 the English associated lovers with the feast of Valentine because on that day "every bird chooses him a mate." The custom started of men and women writing love letters to their Valentine on this day. Other "romance" traditions have become attached to this feast, including pinning bay leaves to your pillow on Valentine's Eve so that you will see your future mate that night in your dreams.

Darn, it's probably too late to help you now, but here's an article with as much as is known about the three men who might have been St. Valentine: http://en.wikipedia.org/wiki/Saint_Valentine

There seems to be much speculation... One legend is set in third century Rome where Claudius II had forbidden marriages because he believed that single men made better soldiers than married men. St. Valentine defied this injustice by marrying young lovers in private. Another legend contends that St. Valentine was killed while helping others escape from a brutal Roman prison. A third legend asserts that St. Valentine fell in love with a young girl who visited him while he was in prison. He sent what is considered the first valentine, signed "from your Valentine," a phrase that has evolved into the holiday's most popular salutation - "Be my Valentine."

I'd post an article I wrote on that, but this site isnt set up for bb/code, so I cant. But google is your friend. And ALL can be found on wikipedia
