Thanks for the additional information.I too was unable to find Juliana on the 1881 census and as she did not marry George Luffman until 1887, and I am assuming she was not married previously, I too suspect she was possibly abroad at the time doing the governess job my mother's cousin told me about as I searched the whole index.
My own Luffman research connections had never heard of Juliana until I threw her into the equation so I suspect I am the first to actively research this branch of the family other than the cousin mentioned above who told me he had "done the family history" and provided me with a copy. This turned out to be a male line tree with names of all the children and wives he had found.It was full of queries and gaps and had no information on the Luffman wives other than their names, the odd date and in most cases not even a maiden name. Not my idea of having "researched the family history"! I am working on the Luffman family presently and have the male line unsubstantiated back to around 1700.Next step - get it substantiated, fill in the gaps and see how much further back I can go. Juliana is, of course "a gap",
I do have a photograph of Juliana if that would be of any assistance to Christopher Foyle.I can easily get it copied if he wants one. I also have a photograph that I believe to be of Emily May Luffman, though there is a niggling doubt that she looks awfully like her mother, so it is possible that this is another photograph of Juliana, though I lean towards it being of Emily.
If there is a connection with the Foyles of books/libraries fame it would certainly explain my unending fascination with books and never ending joy in reading!!
I shall keep you informed of progress, however slight, and look forward to hearing what Christopher Foyle has to say about Juliana.
