Thanks Rob,I've still got to get round to checking the Joseph Hall marriage etc,as ever with these searches I got sidetracked spotting other Boulton relatives!
As far as Frances Wright is concerned I have no definite info of her birth or Parents.The same is fairly true of the Thomas Mountford,but ignoring the submitted entries on the IGI,the only possible birth of a Thommas Mountford who would have been able to marry the Farncis Wright that I've found given in Stoke-On-Trent itself is one whose Christening is given on the 10th of September 1754 to Parents Joseph and Mary Mountford.
Thomas's marriage to Frances Wright is given on the IGI to have taken place at Newcastle-Under-Lyme on the 29th of April 1788.
