Same person?

Do you know who the infant is? If you know when they were born, that would be a good dating clue.

With such a blurred image I wouldn’t like to hazard a guess at the age of Edwin in the group photo. The sitter for the portrait could be 24, give or take. Have you contacted the owner of the Ancestry tree who may have more details about the portrait?

They do look very similar but the right hand 'Edwin' looks thinner and more than a year older - did Edwin fight in WW1? That may account for it if he did.

They could possibly be Olive Mary Lindsey, Edwin's daughter but i don't think they share many features. There is another baby far right but you can't see their face. If it was Olive M it would put the photo around late 1914/1915. Olive M's sister Margaret may be the other baby putting it late 1916 but     
I'm not sure.

 I can't find anything to say he did fight or was discharged from the army so i would say no.
