Douglas, and more particularly its nickname, Doug, had a real romantic swagger in the 1950s and 1960s dating back to swashbuckling Douglas Fairbanks, but today is more likely to conjure up your mom's prom date. Originally a Celtic river name, it became attached to a powerful Scottish clan, renowned for their strength and courage. In its earliest incarnation, Douglas was used equally for girls and boys.
Douglas has been on the popularity list for as long as US records have been kept, for a considerable period in the Top 100, often used to honor World War II General Douglas MacArthur. Douglas currently ranks at Number 601; modern parents might prefer the livelier Dougal.
