Cazz - fascinating insights and a really good online resource from Birmingham. Both of you seem to be indicating that 'lewdness' is something a woman from the rough end of society was accused of......I've not come across any posh tarts or madams coming before the bench (if you'll pardon....)
So, one of the discoveries I made between yesterday eveninig and this mornng is that lewdness was a more ancient law, but that it seems to be taken by the 19th century as the slightly more defined misdemeanor of 'outraging public decency' - lewdness for shorthand. Part of this included a need for the act to have been witnessed by two or more people, who were offended by it.
So whatever these ladies were doing, it seems to have been in 'public' - I suppose anywhere outdoors - as opposed to behind closed doors.
I think there's still a lot to unpick here - thanks for your insights!
