Hello Stuartroxy
Funnily enough I have only just noticed that the marriage certificate of my great great grandparents (Matthew Plant and Louisa Bache) was signed by Emma Gee as one of the witnesses. Is she one of yours? This was in 1868 in Birmingham at St Philips.
It's probably not much help in your search, but I was struck by the coincidence, as I've only been going through the certificates very recently before a visit to my uncle, so if you'd asked a week earlier I probably wouldn't have noticed the name! At least it shows the Gees (or some of them) were still in Birmingham in 1868!
Regards
Tessa
