I’m pretty sure my mom told me that the man driving the car is Albert Green, her father’s father.
He and his wife, Jessie, were divorced in 1913. I know the date because I have a copy of the divorce papers. Apparently, according to the divorce papers, Albert deserted his family when my grandfather was about 2 years old or younger.
I think that this mystery man is also Albert — look at the nose and mouth.
