This is quite exciting because I thought I had reached a dead end. I went to the record office in London and it took ages to find anything because the microfiche are not indexed as with rural archives. I live in Oxfordshire so find it quite difficult to visit for physical searches. But if I do come across anything that verifys our links I will let you know. I do have a transcript of a Voluntary Examination of Elizabeth Jaggers dated 1790 from whitechapel to Clerkenwell with seven children (one was a John) which I can't seem to attach or copy into here. If you can see it I think that the Richard mentioned is my Richards Father and that the mother was Elizabeth Spice but this is hard to prove.
