Pringle Family Portrait

I've obviously been looking at old photos.
This one is of my paternal grandmother's family, taken in 1888, the year of the father's fortieth birthday.
My grandmother is the tall girl in the back with the long curls.

I hope those were really her hair and not extensions.
She was born in 1871 on her dad's twenty-first birthday, the first of
seven children.
In this photo she is seventeen.
The baby on his mother's lap was later a victim of polio which affected his speech.
