Thanks Blongb, that's interesting to know. I had a look at Chris Draper's book "Llandudno before the hotels" last night and it mentioned Wyddfyd and the Williams family.
At pg 180 is a record of "Year rent of Gloddaeth Estate belonging to Sir Thomas Mostyn". At No 23 is listed Tenement Whyfud (incorrectly spelt) and under tenant is listed Roger Williams. For the entry under yearly rents the figure due looks like £ 0 The record doesn't show the year but I expect it to be in the early 1800's
Chris Draper also mentions this about Wyddfyd. "Wyddfyd had, in the medieval period, been a very important farm that gave its name to one of the Great Orme's three townships but 19th century Wyddfyd Farmhouse was no more than a small single storey cottage with its landholding reduced to 28 acres. The ancestors of John Williams had occupied the farm for many generations and the family played a prominent part in the community. John's wife Elizabeth had a beautiful singing voice and the couple's son Benjamin became a hugely influential musician in the Chapels. Besides running the farm John Williams owned the shop in Old Road run by his son and daughter, Dafydd and Jane"
The shop in Old Road was near the Kings Head and was called Siop TY Newydd and sold drapery and groceries
