Carson is a Scottish patronymic surname that means 'son of Carr.' The name Carr comes from the Old Norse kjarr, meaning 'swamp' or 'marsh,' and was likely a nickname for someone who lived near a marsh. The Carson family name has roots in Scotland and Ireland. As a first name, Carson was relatively rare until the late 20th century, when it began to gain popularity in the United States. It surged in the 1990s and 2000s, influenced by the trend of using surnames as first names. Carson has also been influenced by popular culture, including the character Carson Drew in the Nancy Drew books and the television personality Carson Daly. Its appeal comes from its surname style, its modern feel, and its strong, approachable sound.
