Mabon Abraham

A Memory of Cwmavon.

My Great-great-grandmother on my Mother's side of the family was a cousin to William 'Mabon' Abraham, the miners' leader and first President of 'The Fed'. I was wondering if there was any way anyone out there reading this may be able to help me fill in some of the blank spaces in my Faniky History, please? Or perhaps point me to a local Society in Cwmafon/Llanfabon where I may find what I am looking for?
My mother remembers  Margaret Carpenter (nee Abraham), her great-grandmother, who died when my mother was a young girl and would like to learn more about her family.
Sincerely,
Caroline Scott.
