Hi
No, we dont know what happened to Brian George at all, he seems to have disappeared as well.
I know that Viola/Violet was actually Violet Ruth Gunthorpe and she was born in 1892 in Herefordshire, the daughter of John & Louisa Gunthorpe. In the 1911 Census she was living with her family in London and worked as a typist at (we think) McCorquodale Printers. I have checked the ages on the 3 marriage certificates we have for and they do tally.
I can only imagine that Viola/Violet went abroad somewhere, eg Australia, Canada or somewhere else. Once I learn how to do a general worldwide posting on Rootschat I will do, but at the moment I can't see how to do it.
