Hello Hugo and Cambrian,
I had an idea that the soldiers were GIs, so am pleased to have this confirmed.
I have other photos of family members in a similar style to this and think that they were all taken by street photographers.
I don't know where Elizabeth lived other than 2 Clement Ave in the nursing home. It is possible she stayed with another member of the family in the town, or Llandudno Junction. She has proved to be an elusive lady after 1894. There was an effective split with her husband in 1894, I won't go into details here. She was in Brighton in 1905, in Camberwell, London with Frances Gertrude Kerridge, one of her two daughters, in the 1911 census. After that she disappears.
The daughter she was with in 1911, Frances Gertrude, sometimes shown as Gertrude Frances, went to be "Hotel Proprietoress" of The Gwydr Hotel, Dolwyddelan. Frances Kerridge died there aged 28 in 1913. It is possible that Elizabeth followed her daughter and lived with her until her death. The Kerridge relations had pubs and hotels in and around Llandudno, could be one of them put her up.
Helig.
