I did initially think the girl may have been Amory's granddaughter through her first marriage as I think they have similar noses.
I'm not the best on faces, but I had wondered if there was a likeness in the noses. Could Amory have had a daughter or another granddaughter that you haven't yet found?
Hi Arthur, thank you for your interest.
Following your suggestion, I have rechecked my research and I can find no evidence of a daughter to Amory Dorsett and her first husband Arthur Fowler, just the one son born in 1920.
Her son and his wife had only one child, a daughter born in 1951. The son and his wife have passed away, but I am reluctant to name them here as one was quite recent. I believe Amory and Arthur Fowler's granddaughter is still living.
Maybe someone from the Fowler family will find this post one day and solve the mystery.
By the way, the man in my profile photo, James Dodson, is Frederick's father.
