My mother was adopted by Gwen du Maurier in 1919. I was particularly interested to read the correspondence to her from J M Barrie but came unstuck because of his handwriting. Has anyone deciphered these letters?

I see that Yale University Library hold many of the Llewellyn Davies families papers and have a folder (83) in Box 2 containing letters sent by J M Barrie to Gwen between 1910 and 1920. Can anyone tell me if these are the same letters shown on this site or if they are different?
