It is remarkable that Penrhynside was know as "Holy City". I have never heard of that before. When I lived in Penrhyn Bay in the 1960s I was of the age to be confirmed. The Confirmation classes were held in a building in Penrhynside. This was linked to St David's church on Glan y Mor Road. It was just off the main road at the top of the hill.
I think that the answer to our problems might be in the non conformist records, that is if they survived and are in the public domain. It is interesting to note that Pierce Jones married in the Sion Chapel in Conwy.
Robert Jones was the Informant of the death of John Jones in 1861. This suggests he was related, or had a close connection to him. The Family Trees on Ancestry, which show John Jones to be the son of Evan Jones, do not mention a Robert Jones in their trees.
My theory is that John Jones was the son of John and Anne Jones and that this is the family living in Penrhynside in the 1841 census. The household is shown as:
John Jones, age 65, Miner, born in same county.
Anne Jones, age 60, born in same county.
John Jones, age 25, Mason, born in same county.
William Jones, age 20, Miner, born in same county.
They are living at Pen y Park which was immediately before Gloddaeth Isa.
In the 1841 census, I found Robert Jones living in Bryn y Gwynt, a few places along and his household is shown as follows:
Robert Jones age 30 Miner, born in same county.
Elizabeth Jones, age 35, not born in same county.
John Jones, age 8, born in same county.
Hugh Jones, age 4, born in same county.
Robert Jones, age 3, born in same county.
William Jones, age 1, born in same county.
There is a family by the name of Roberts living next door to them. Head of household is Owen Roberts.
It would be good to hear what Mull finds on his visit to Llandudno.
Helig.
