Although James Bruton Shearmur was in Gloucestershire for both the 1871 and 1881 census it looks like he took a trip to London. James Bruton and his wife Eliza Mabbett were not married until 1876 in Dursley, Gloucestershire so perhaps they were in London for the birth of the baby.
From http://www.rogerco.pwp.blueyonder.co.uk/ the woman's dress looks like it is an 1870's dress.
As most of the Shearmur's were in Gloucestershire except for Arlette who would have been at least 34. I think the woman in this photo is younger than that so I would like to say this couple is James Bruton Shearmur and Eliza Mabbett but am open to suggestions as to the identity of this couple.
Isn't it fun trying to work out who is in the photos.
Anyone out there who can verify the identity please?
