Setting: Basically, mid-Tudor England.
What I'm wondering is - would it be outside the realm of possibility for a traveling band of mystery players to incorporate a few female actors? They stick to quite rural areas, so I was thinking it might not be too reprehensible; the few pages I've found that do mention the sex of actors seems to say that there possibly/probably wasn't a moral reason they didn't act and anyway, the character could easily be a seamstress or set-mover or something. But I'd like her to work on the stage, as long as that wouldn't be totally anachronistic.
