Realistically though she's like 5% Dutch and 7 generations removed from whoever stepped off the boat. Her parents were legit white trash.
That doesn't make her oppressed, but not privileged either. Just painfully mediocre.
Also of note is the fact that her mother is also probably cluster B, is a serial liar in her own right, and went through a messy divorce with pops when Chelsea was a teen. This is notable because New York state was one of the last to legalize at-will divorces. Meaning that one of them had to provide proof the other was cheating or abusive. Or, rope Chelsea into backing their story.
I vaguely recall an earlier report of mom claiming that dad sexually abused Chelsea, I don't know if anyone else does.
I wonder if divorce filings are public record?
