Well done Toni!
Was there by any chance anything regarding those seemingly implicated but not arrested? I'm thinking mainly of Ellen Wheeler Jr of course, but also perhaps of Alfred Cullmer Jr, although Alfred's involvement in the "Fire Business", if any, would have been before he emigrated to Australia with his wife Eleanor in the early 1880s, so probably would not have been included.
I've made no progress on Alfred Jr in Australia due to non-availability of census data.
It's a pity there are no photos - the only Culmer photos I have are 2 of my great grandmother Rosina, both undated.
