What?! Actresses Sydney Sweeney and Marilyn Monroe are related? We had an inkling that both had somewhat similar pathways to success, and both brunettes became famous as blondes, but this is downright weird! According to MyHeritage, an online family history platform, Marilyn M is Sydney S`s ninth cousin once removed. The latter`s father, Steven Sweeney, and the former`s (biological) father, Charles Stanley Gifford, both trace their ancestry to a man called Ezra Perry. Wow! No wonder The Housemaid star seems to like billowing dresses a lot.
