Sidney
A contraction name, Sidney comes from Saint Denis and is related to Dioynsius, the Greek god of fertility and wine, although another theory is that it derived from an Anglo-Saxon place name, meaning 'at the wide island.'
Sidney is an aristocratic British surname--as in the Elizabethan poet George Sidney-- and later attained a further measure of distinction through its association with the self-sacrificing hero of Dickens's A Tale of Two Cities, Sidney Carton, and with Oscar-winning actor Sidney Poitier.
In the US, Sidney was most popular in the 19-teens, when it was in the Top 100 for that decade, but has gradually declined, especially after the girl's name Sydney burst into popularity in the 1990's.
