The Procedings of the Old Bailey, 1674-1913, is now online and fully searchable. A quick inquiry yielded over 400 cases in which Litchfields and all sorts of potential ancestors were involved in such crimes as highway robbery. Litchfield-street in Soho (also given as Seven Dials) also seemed to be a site of much skullduggery.
I am delighted- it’s the kind of resource that makes the incurably historically-minded faint dead away. Now I’m waiting for similar resources, for, say, qadi court rulings from Ottoman Egypt… searchable in Arabic, of course.
