The Munsters actress Beverley Owen died, age 81, following a two-year battle with ovarian cancer. Owen (born Ogg) passed away peacefully last Thursday while surrounded by friends and family at her home in Vermont, according to TMZ. Beverley originated the role of Marilyn Munster - the 'ugly' teenage niece of Frankenstein and a female vampire with a werewolf for a cousin - in the first season of the CBS sitcom. 'Beautiful Beverly Owen has left us,' Butch Patrick - who played Eddie Munster - wrote on Facebook Sunday.
