To resurrect a very old thread, but I've found her!
I knew George Campion, son of Annie and Harry, eldest brother of my grandad died in Ludgershall, Wiltshire. I since found out after Harry died, Annie went to live with George (grandad told me the other day).
I know Annie Badger called herself Polly Johnson on her marriage certificate.
So, once I found Annie died in Wiltshire I searched for her death. No deaths for Annie Campion, but there was one in 1963 for Mary J Campion. A litle bell rang, weren't the names Ann and Mary fairly interchangeable? I Googled that, and my search confirmed my thought. It also suggested Polly and Mary could be swapped. Thats 2 coincidences.
On the marriage certificate Polly's father was John Johnson.
I checked the 1891 census for Mary. I found Mary J with a father called John. Another coincidence?
I ordered the death certificate. It came today, Mary J Campion, widow of Harry Campion, death registered by George Campion. It's her, I found her and I finally know her real name. I feel quite teary. It's taken nearly 2 years to find this.
