Harry Potter

Interesting fact about that name origin

“Merope is the faintest of the stars because she was the only of the Pleiades to have married a mortal. Her sisters had relations with gods and bore them sons, but Merope married Sisyphus and lived on the island Chios. Merope gave birth to Ornytion (Porphyrion[6]), Glaukos, Thersander and Almus. The star Merope is often called the "lost Pleiad" because she was at first not seen by astronomers or charted like her sisters. One myth[7] says that she hid her face in shame because she had an affair with a mortal man.”

Definitely makes sense as she married a Muggle.

And yes, Sisyphus is the guy with that big rock.
