John Stamos is the oldest child and only son of Loretta, a former swimsuit model who was raised in England, and Bill Stamos, a Greek immigrant and restaurateur from Paraguay. His family's last name was originally Stamatopoulos (Greek: Σταματόπουλος) but his paternal grandparents shortened the name to Stamos after they moved to the United States from Greece. ('-poulos' is a common Greek suffix in surnames, meaning "son of"; 'Stamato-' is the root.)
Uncle Jesse and Aunt Becky dated in real life? John Stamos revealed Friday that he dated his "Full House" co-star Lori Loughlin, however it was before they played on-screen husband and wife in the popular sitcom.
