A Pool Shill?

Today, August 9, is National Billiards and Pool Day.  It is noted as such on two of the "national day" sites (Days of the Year and List of National Days), although neither has any information about how it started.

I'm celebrating the day on my blog because my mother used to tell me about how she and our Aunt Sam (who was not our biological aunt, but my mother's close friend, so we called her "aunt") used to play pool.  My mother, as she told the story, was not that great a pool player, but Sam was.  So my mother got someone to play against her, and she would lose, then setting up the poor stooge to play against Sam.  That made my mother the shill.

Coincidentally, I actually found photographs in the "photo bonanza" showing my mother and someone I believe to be Sam playing pool!  Some people in other photos are playing pool or look as though they are in the same location.  I don't know who most of them are, but all the pool players are women!

This is the only easy identification, because it's my mother.
I think the woman on the right here is the one in the last photo (see below).

I think this is Aunt Sam, but I'm not sure.

Aunt Sam had a daughter named Cathy.
Could this be her?

This photo makes me wonder who the photographer was.
It could have been my father, but I don't know.

Here's the girl from the previous two photos,
with another girl and a man.  No idea who they might be.

And here's our final player!
Unidentified, of course.
