I noticed Sean Smiths pictures and have an idea of their names. I could be wrong and open to correction.
I think the woman on her own is a Mrs Carney who had a sweet shop in castle st, and I am almost certain that the fella with the wellington boots and peak cap is Tom Carney from clydagh pontoon rd direction. He was better known as the horse Carney. Im not sure who the lady beside him is I think she also was a shopkeeper on main st.
