I have a few more details that may help find my Grandmother.
Since starting my research I found that her father was Walter Callow born 1881 and mother Elizabeth Annie Copson born 1876.
Ada married my Grandfather John George Petford and had a daughter Irene Elsie May who was born in 1925. Ada left in 1925 when Irene was 9 months old
Ada later had a son Raymond Petford 1933 -Unknown father, think he was adopted out and then I think she went on to marry Alfred Ewer in 1939 then Barry H St Ledger in 1943
Can anyone help me find what happened to her my email is email@example.com
Thank you Janice
