I can't see your photo but the family in Llangedwyn is probably the Watkin family. There was a Sir Watkin there in the 1960, big happ, estate etc. Also known as Watkin Williams Wynne. In the 1800s the family held competitions at yearly shows and the list of prize winners e.g. best kept cottage, best beans, peas etc were reported in the Wrexham Advertizer newspaper which is where I found someone I was seeking in Llangedwyn..
