Hello all, I'd no idea Minnie Jane's knees or legs would attract so much attention.

I can't offer any explanation about any unusual appearance, and wonder if she has just slumped down in the chair to give a better composition with the other girls.
There are pictures of her standing, and her only known disability was that she ended up fairly deaf, (she used a large ear trumpet, apparently).
She worked as a sorting clerk and telegraphist in a variety of Herts & Beds Post Offices, and was eventually awarded a Civil Service medal for long service, (I found details in the London Gazette).
I don't think she was particularly tall - it's Lizzie that looks like she was probably the tallest. But my grandfather Harry's world war one service record claims 5' 9", but when pictured beside my father (6' 1"), they are very much matched, so I tend not to believe reported heights anyway.
Very interesting that other photo of 4 similarly dressed.
I don't think mine relate to a uniform or a club membership. Certainly church wise the family were Strict Baptist, so no dressing up, or chorister possibilities there.
Here's another poor image of the family.....
