Strays from Penticton, BC. 1921 - A family photo?

" L. D. Cafe

Penticton, 1921

Mother, Mel, May & Billie"

Do these names ring a bell?

Great photo! 

But not quite enough info, yet. 

I suspect May and Billie may be visiting Penticton.

Do let me know if you recognize anyone or the names...or the car.
