Hi Katharine
Florence James was my Great Aunt.My Great Grandfather was James James,my Grandfather was William James(twin Brother to Samuel)and brother of Florence.
William married Dora Charles.They had 5 children one of whom was Percival who was my father.
I have only just started looking at the family tree and you appear to have more information than me.I am still searching and will contact you if I find more information.
