Mystery mat shed group?

This photo is a match as far as the mat sheds, but the people are still a mystery. I believe the seated caucasian lady might be my grandmother Maud Wilhelmina Hunter but I’m not positive. Also I’d originally thought that maybe the man on the left was my grandfather Tobias Hunter but I’ve pretty much ruled that out. Allowing for gain or loss of weight, hairline changes etc I’ve made comparisons but finally it’s features like ear shape and pattern that rule him out.
