Does any one know any information about the Huguenot surnames from Plymouth  , I’m trying to trace my family ancestry in the surname of Down . But I can’t easy find much info , I know our surname was changed but I’m not sure which way to go. My father mentioned the surname de D’aud , de Doud, or de Daudé when I was small  . If some one could shed some light I’d be very pleased. Thank you .
