Llanharan group photos 1920s - any info

[lcsnor]

These pictures came from my Nana's house.  They look like they are from a sunday school outing perhaps.  I think we can identify a couple of the adults but although my mum did write the names of some of her uncles and aunts on the back of the childrens' picture we don't know which kids they relate to.
My nana's maiden name was Gore and she grew up in Llanharan.

If anyone knows anything about either of these pictures, can identify any of the people in them or wants a better copy, please let me know.
