Re: Family name Pigford
I have made an list of all Pigford and Piggford births, marriages and deaths as recorded on the civil indexes in London and there are two Emily Pigford births recorded there that might fit your great grandmother. Both are registered in Chester-le-Street, Co. Durham, but in different districts or parishes.
1. Emily Pigford, birth registered in the March quarter of 1887. The reference for the full certificate is Vol.10a, page 463. The certificate would give you the parent's names.
2. Emily Pigford, born 9 January 1897, daughter of Matthew Pigford and Jane Mason (originally Clasper). The reference for the full certificate is Vol.10a, page 515. I know more about this Emily's details as the records for this part of Chester-le-Street are held by the Stanley, Co. Durham, registrar whom I visited earlier this year. But the records for the other Emily are held in Gateshead (I think), and I haven't looked into those yet.
What else do you know about her or Thomas Fawcett? None of the marriage or death indexes have an Emily that would fit either of these births, so did your Emily marry outside UK? Where did Emily die?
Matthew Pigford and Jane Mason (Clasper) had a second daughter, Elizabeth, born 25 May 1989. I have no index record that would fit as the marriage for this daughter either. Perhaps the entire family emigrated?
