Old black and white pictures from Grace - unknown location/children/time period

These small pictures (approx 1.5 in x 3 in) were in a white envelope.  On the front written in Ellen's handwriting:  "unknown, m. had these in this envelope I think"

M = mother/Grace Miles

I am guessing these could be pictures of possibly Gloria and Gary in Ohio??  Because the clothing suggests the time period of possibly the 40's and 50's??  They of course could be children from other family members as well both on the Miles side as well as the Hirst side, so I'm very unsure.  I do not think this is the farm in Mineral nor the farm in Vermont because it doesn't look at all like it.
