I don't know much about researching in Wales - and I currently a have an awful cold! - but I found this one interesting.
I imagine the reason researching is so difficult is because birth, marriage and death records outside of the Church of England are generally harder to come by. It sounds as though the family had been Methodists for a long time, and I'm not sure about the availability of records for this denomination.
I focused in on David Hughes, as we have more information regarding his birth and death dates. We also know that he was a tinman. This looks like his will, which is free to view via the National Library of Wales:
https://viewer.library.wales/341156#?xywh=-664%2C0%2C4109%2C3449&cv=From it, we know the following:
- He had at least 5 daughters, namely: Jane, Ann, Mary, Elizabeth and Hannah.
- He had a son named Hugh (already known).
- His wife was
Elizabeth.
So we know that Humphrey Edwards' daughter (I'm not sure why you refer to him as Prichard?) was called Elizabeth.
I can see the baptism of David & Elizabeth's daughter Hannah on 9th August 1812 in the Sion Chapel, Llanrwst, which was Calvinistic Methodist.
In 1838, the minister of this chapel was a Hugh Hughes.
I had a look through entries in the will indexes, and the only one that really matched was one from 1869 regarding "Hughes The Reverend Hugh" who was "late of Brynhyfryd in the parish of Abergele... Dissenting Minister... who died 1 February 1869." It was proved by a Margaret Roberts (wife of the Reverend Robert Roberts, Dissenting Minister), who was his daughter.
I had a look through the newspaper archives, and an article in Welsh popped up. Now, I don't understand any Welsh but I picked out the following key parts:
"74" - I think this refers to his age at death, making him born c.1796, which would fit.
"Llanwrst" is mentioned.
"David Hughes" is mentioned.
"Capel Seion, Llanwrst" is also mentioned. I believe this is a reference to the Sion Chapel.
I think this is almost certainly your man!
If you want a full translation, your best bet would be to post it on here, as I'm pretty sure there are a few Welsh speakers. It's free to view on FindMyPast: Baner ac Amserau Cymru, 03 February 1869
