Genealogical research conducted by MyHeritage has established a distant familial connection between actress Sydney Sweeney and Hollywood icon Marilyn Monroe. The study identifies the two women as ninth cousins, once removed.

The lineage traces back to Ezra Perry, a 17th-century English settler in Sandwich, Massachusetts. The connection was determined by following the paternal lines of both actresses: Sweeney through her father, Steven Sweeney, and Monroe through her biological father, Charles Stanley Gifford.

The investigation was prompted by frequent cultural and aesthetic comparisons between the two stars by fans and media.
