Many thanks for the response.
I don't have very much on the Stafford area. My main interest has been with the Dudley area - but rather like you, I hit a brickwall with being able to find where a Joseph Hillman (d.1803) was born. He married an Elizabeth Allen in 1780 in Hagley,and they are both buried in Dudley but I can't nail down anything prior to that. I've pretty much covered their descendants! I've got loads of part trees of Hillman's from neighbouring parishes and further afield (which is why I picked up some stuff on Stafford). I recently added a certain amount on a descendent who had gone to Illinois. I've scoured Dudley, Worcester and Wolverhampton archives (as well as having spent a lot of time at the Soc of Genealogists in London) but obviously I need to go back over things.
The marriage detail I have is 1 May 1786 in St Mary Stafford - source LDS Familysearch. Margaret Shaw b 13 March 1764 in St Mary, Stafford (parents William Shaw and Ann) - source LDS Familysearch. This is the same source as for the 1765 birth of Richard in Dudley.
As for descendants I've got a certain amount, mostly gleaned from Ancestry. Happy to supply any further details but I suspect you have done a forensic job whilst I have just done an armchair one on this line!
