I’m sorry, but every time I see “Marsh family”, I think H.P. Lovecraft and “Innsmouth”.
You’re better read than me. Maybe that’s why they adopted that stage name. But never having read Lovecraft, I wouldn’t know.
Any every time I see it, I think of Randy Marsh from South Park. Like Season 12, episode 6, heading west to find some internet, like Tom Joad.
