Barnabas

Barnabas Marsh is a minor character in the H. P. Lovecraft story "The Shadow over Innsmouth". He is the grandson of Obed Marsh, the founder of the Esoteric Order of Dagon. During the events of the story, he owns a gold refinery, but he apparently gained the "Innsmouth look" due to his mother being one of the Deep Ones, humanoid creatures who are worshiped by the order.
