Would these photos help? I know who the young man on the right is, Herbert, he was born in 1909.
The one on the left - the original picture I posted - is either his father or his brother.
The lady is Herbert's mother and either mother or wife of the original picture. Her picture was taken in 1929 and I would think in the same studio as the one of Herbert (same background).
The more I look at these pictures I think the young men were brothers as all three seem to have the same nose. What do you think?
