Hi Catherine

Possibly not really relevant to your current research but relevant link in John Roberts' ancestry - David his brother remained at Pyrse and married and was with children by 1871:

The Richards of Brynmelyn and Roberts of Pyrse lived within a few miles of each other.

Llanfor is approximately 7 miles from Llanuwchllyn with Llanfor only a mile from Bala:
