I have had another look at the Public Member Trees and there seems to be one with a closer link to Pamela Ware, than the previous one I mentioned.
The owner of this tree is - donnaw192 and it is the Wilkinson Family Tree.
They have a Pamela Riley b. 1905 and Pamela's parents were John Thomas Riley and Edith Eleanor Ware b. abt 1873. Eleanor would be Pamela Ware's siter.
This seems to be the best link I am going to find. So I may send the letter there - when I contact the Tree Owner and get an address.
What do you think?
