Hi
Came across this thread as happened on the mystery Julia James via the de László archives.
I am not sure whether there has been some mixing up of families with the same name? It can be very common and confusing if you are certain you have the right person.
To start at the beginning. This JJ was supposedly born in London in 1890, right? That year tallying with her supposed death age.
There is only one Julia James born in London - on 2 Jan 1890 at 62 Marchmont Street, Bloomsbury. Father is Thomas Joseph James, a bookmaker. Mother is Mary James née Stevens.
Thoughts?
