Unknown Appleby or Gilbert Women?

So I found a bunch of Photos hidden in an Album, but they are not labeled.

Does anyone Recognize this group of Women; they appear to be sisters or close cousins. at the bottom it says 231 Main, Marlboro, Ma Company Called "Folsom"

My father guesses it could be Gladys (Appleby) Gilbert who was born (1897 - 1989) in Providence, Rhode Island or her Mother Elizabeth Ann (Green) Appleby 1858-1927 who came over from England.

They were in my Grandma's Album.

I'm hoping someone can help tell me anything about them.

Who are they, time frame of photo, and anything else anyone knows.
