Hugo, my family also lived there and from your photos on the "people" page obviously knew your family well, John Thomas was my great Taid and Gwyneth was my great Aunt. My Grandad, John Edgar Thomas was born in Pen Morfa Cotfages. Last night was a bit of a revalation to say the least as Taid was dead before my mum was born, it was lovely to meet him and to see Auntie Gwyneth as a child, I knew her as a fabulously dressed older lady.
Anything you know of their time in Pen Morfa would be of great interest!
