Doesn’t look like a twin to me. But then we can’t see the whole face. Once again, we’re only seeing part of a whole. If you were to see the entire thing, it may look completely different.
chicken - I think you can safely give the idea of twin Stanley Anns a miss, or at least go and try to find any evidence there were two of them. A theory such as that needs to at least indicate some advantage to hiding an individual throughout their life. It’s easier to add someone to the narrative than wipe them out.
Well, it does look like a twin to me... A school yearbook would probally do the trick with the names listed. There is no census records in the archives to prove— i have no idea if stanley anns BC would be labeled as a twin— not sure—( i cant find it anywhere) I dont know how to prove it.
