Absolute guesses here. Could the 3 boys above, presuming they are different children, possibly be the three boys in the photo below with their father – possibly John Bradley, son of John Henry Bradley? The breeches in the boy on the right tally with the ones in the photo. Photographer Earl is different though to Bennett!
Is the lady in the middle, Kate Nash Bradley, John`s wife and mother to the three boys. Who is the boy on the right? Where is daughter Kate? So many questions.
