Bowman or Crogent Photo

This is a tin photo which was passed down from my Nana, Florence Mary Bowman. The problem is that nobody remembers who it is a picture of - a classic family photo mistake. Does anybody have any thoughts?

I am guessing that this may be a photo of William and Sarah (Cartmel) Crogent with their two oldest children, William and Ellenore. That would be Nana's Grandparents and her Aunt Nellie and Uncle Willie. The ages would be about right and would put the date of the photo at about 1893. They lived in New York City at this time.

Any thoughts anyone has based on other pictures you may have or the use of tin photos or the clothing worn, please feel free to comment.
