Hi Yendis & Jorose,
Jane is with her family in 1841 & 1851, living in a pub run by her mother, it seems unlikely that she would have left and met William in London or elsewhere. They must have 'got together' around late 51/52 to have left in 53 to Australia. She seems to have had a very close family, all together in the area and in each others houses over following censuses.
Yendis, I am sure there must be plenty of Theatre Museums in London, like you I am in Aust and rely on the internet, and all you wonderful people on rootschat! The Era newspaper was the main one for theatre reviews, and I'm told, a paper called the Theatrephile, but am unable to find this one. Maybe I need an art expert too?
I have had a quick look at the Dibdin Pitt line before but will go back to this a bit more thoroughly, instinct ruled it out but I can't remember why.
As to Sunderland, previous advice says that this was part of a county theatre circuit, including Birmingham, that it is likely that William was part of. Maybe meeting Jane at the pub?
I do have a subscription to both Ancestry & FindMyPast, so will look for the marriage of TH Pitt there, the 41 census you mentioned earlier Jorose definitely indicates that he is the son/relative of Dibdin Pitt (mother Sophia). I would like to see his, or Dibdin or Sophia's will but have looked at the index for 'Pitt' wills on NA site before and not noticed these?
Thank you, Jo
