There were generations of Addis family at a farm, at Didley, Wormbridge, parish of St Devereux and people from that family are still in the area. My cousin Maisie Phillips knows them well. A member of this family went to Crickhowell many years ago and recently published a photohistory of Crickhowell. One of their children went back to Didley to live for a short while. No idea if they are connected but as they are less than 4 miles apart, probably are.
