A male given name transferred from the surname.
"Many people find it amusing that Darren is such a popular first name despite originally being a family surname."
Unknown. A twentieth-century invention, possibly from a rare Irish surname of obscure meaning, possibly from Dara or Daragh, meaning "oak". It is also the name of an old silver mine near Aberystwyth, Wales. The name became popular, particularly in the UK, because of a character in the 1960s American TV series Bewitched, actually spelled Darrin. (person with sense of entitlement): As a rhyming equivalent for Karen.
