Haha! John, it's really looking like it's her, isn't it!
Clues from the records so far, when comparing Caroline and Dorothy:
1. DOB matches
2. Father's forename is William
3. He's deceased before 1929 (when Dorothy married)
4. Shepherd and Langley are the two maiden names Dorothy used; Shepherd was Caroline's married name and Langley was her mother's maiden name
5. Dorothy, we were told, grew up with an aunt in Blue Bell Hill; Caroline was in nearby Maidstone and Bearsted and indeed appears with an aunt in the old census
6. Dorothy first appears in 1916-1917 (in London); Caroline marries Shepherd in 1913 and then vanishes (Admittedly not yet done an extensive search for the vanishing Caroline, however her husband Archibald Shepherd seems to be with someone else in later records)
7. This would make my grandmother and Mabel's great granddaughter "1/2 1C2R", which the amount of shared DNA would support
Looking highly likely, isn't it!
Thanks again!
Glen
