Now that we know...

Now that we know all the pertinent information about Susan, here's another one that's a mystery to me... though I do have a guess.
First, on the right, we have Lillian who, apparently, had tried a new shampoo that day. It sure made her hair look... different.
The lady on the left. Gosh, she looks about 30 years older than Lil but I have a feeling the age difference isn't that great.
Is this Gladys? (Angus Jr's sister)
You know, I only met her once, at my father's funeral, but she made an impression on me. This kinda looks like her.
