Who are they?

Two ladies with an Irish/Scottish look.

Back Row Adults L to R

Miriam Walter Knox, Sophia Bernard, Vivian Dolan, William Robinson

Front Row L to R - ? 5 children ?

All subjects L to R
Back row left side - child, child, Vivian Dolan, adult male holding baby
Back row right side - child, child, ?Violet Dolan?
Foreground - child, child

I have long thought this was a photo of my father, Anson Herrington.
However, I have no evidenc of this other than the subject's stance and general look.

Circa: 1931
This photo shows both Herrington and Dolan family members.
There has been much speculation about who several of the subjects are.

Back row L to R- Uncle Harold Herrington, ?Uncle Arthur (Red) Homan?, ?, ?, ?, ?, ?, ?Cousin Omie Herrington?, Anson Herrington
Front row L to R- Aunt Gertrude (Vandoome) Herrington, ?, ?, ?, ?, ?, Vivian (Dolan) Herrington

Back of picture writing - "To Viv & Andy from Ma"
The lady on the left appears to be Viv's grandmother, Sophia Bernard Dolan.
Most likely guess is that the center lady is Viv's mother Miriam Knox Dolan.
No guess as to who the lady on the right is.
