Eleonore Green would have been a Countess Rosenborg.
I wonder about the three young men. They look a lot like Thyra's sons, but they are not of the right age, and two of them were of course already dead. The youngest boy, in the lower right hand corner, looks almost identical to Thyra's middle son, Christian, who died, I think, in 1901 at the age of 16.
Could they have been Thyra's grandsons, the 3 oldest sons of Ernest Augustus III and Viktoria Luise? (Ernest Augustus IV, George William, Christian)
The youngest could have been Christian, born in 1919, and the middle one could have been either Ernest Augustus IV or George William, born in 1914 and 1915 respectively.
I'm not sure about the young man in the top right of the picture....
Any thoughts?
