New Year's Day, 1917! That's clearly Marguerite front and center, with Ethel just behind her.
I'm guessing Frank and Minnie (Marguerite's and Ethel's parents) are at the far left.
Is the tall guy in back Frank junior?
And are the other two kids Lester and Billy? Or who?
And who are the couple to the right?
(Barbara Cox and I are going with the following names, from left to right:
Frank Stoakes, Minnie, Billy, Frank, Ethel, Marguerite, Lester, unknown, unknown).
