Hello, thanks all of you for your help and interest.
Since I last came on here I have got some interesting snippets from Google (union history, including one of the links above), and from free access to the Times Archive.
I have no census access though so Oly, thanks very much indeed.
Another rootschat kind person found him in the 1871 mistranscribed as Richard, not Pickard.
thanks again, will be back soon when I have time to go through info. xxx
cheers all, Jen
