Can't help with Florence but your George Matthew Abell is very likely to be George Mutlow Abell Solicitor from Barnwood in Gloucester. Wife was Mary Ann Francis. They had several children but I don't have info on them all. Those I am aware of are:Francise Hameline Asgill, Blanche, Augusta Laura Matilda (my great-great grandmother), Harwood, and Rowland Leslie. You can get further details from Phil Preen's family history pagehttp://www.thehat.free-online.co.uk/genealogy/FamilyHistory.htmhttp://www.thehat.free-online.co.uk/genealogy/FamilyHistory.htm. I understand Phil has details about the other children.Phil is a decendant of Rowland. Contact details via his web site. Nigel Abell (email@example.com) is also related to Roland and may also have useful info.
Augusta married John Walker Tandy and migrated to Australia. I have not heard any family talk about others migrating but will see what I can find on Charles Howard Bradley for you.
