The mother in this picture looks like Caroline Doster, my great-grandmother, and I am going to guess at the children based on this assumption. Presuming that if the littlest girl is Caroline, then this picture must have been taken after the death of Elmer in 1912, as she was three when that happened, and looks much older than that in this photo.
