Hello, I found a picture that my grandfather had.
I believe it was taken in the early mid 1920's either in Vatta or Budapest.
The person on the right is my Grandfather Istvan Csaszar (illegitamite child of Valeria Gobertina Erdody).
I do not know who the person on the left is.
Relations to the Erdody and Odescalchi family may be a clue.
Thank you.
