Chadwick is a unisex given name of Old English origin, derived from the elements "cæd" meaning 'battle' and "wic" meaning 'village'. It was traditionally used as a surname but has gained popularity in recent years as a first name for both boys and girls. The name Chadwick is often associated with its most famous bearer, Sir Arthur Chadwick (1853-1930), an English engineer who invented the modern flush toilet. However, it is also notable as the birth name of actor Paul Chadwick and musician Chad Smith. The name has been used in various forms throughout literature and popular culture, such as in the novel "Chadwick, King's Scholar" by H. E. Marshall and the TV series "The Secret Circle.
"Chadwick is quite rare; it's only been given to babies in 2 years out of over three decades."
