I'm still collecting material researching this character. There are bits and pieces to be found in old publications, preserved and floating around out there on the interseine. Just recently I'd run across a reference to something else Bickley was involved in, the "Wayne Circle of the Brotherhood of the Union".
The more I dig the more Bickley looks like another operative so I'd temporarily concentrated my efforts on trying to sketch out possible connections to European powers such as were long ago documented for J. W. Booth. So far there's nothing I'd hang my hat on but I think I'm on the scent.
