The Barrymore and Drew ancestry she has is particularly bonkers. She comes from an unbroken (though slightly zig-zaggy on a family tree) line of actors going back literally 200 years, many of them with notoriously unhappy personal stories. Celebrity gossip is that her daughter(s) may eventually act, which would bump it from 6 to 7 generations.

I knew she had a troubled history, but that's just sad. My older sister said she once drank alcohol she found around that age, but that was a mistake. Who would knowingly give a 5yo alcohol?

Plenty of horrible parents outside of showbiz,

The famous folks get more attention.

I didn't think of it like that, but it's a wild image.
