I'm stuck with Walter's father. I've found out that he had at least one sister called Rose but there are some other Bamford relatives that have come into the picture, at this time I think they're cousins: There are two maiden aunts, one not known, the other called 'Aunt Lizzie' Bamford. They were living in Pilton, Nr. Lilford, Northants in 1890/1930. Don't know if this is your Elizabeth.
