Artizan has a Bill Sikes and The Artful:

It was published in 1837-1838, right at the start of Victoria's reign (but not set much earlier, as it is in part a critique of the New Poor Law of 1834), so it's closer to the Napoleonic era than to the late Victorian period that so many adventure-oriented ranges draw on. It might be worth checking out Napoleonic civilians (especially as the poor would have worn second-hand or hand-me-down clothes). Civilians for the Indian Mutiny or New Zealand wars might be useable, but I'd be cautious about anything much later.
Why is it that you don't want to use the Foundry pack? Its Fagin and Dodger are nicely accurate versions of Ron Moody and Jack Wild from
Oliver!, though some of the other figures in the pack look rather shoddy.
