I have just been given some information about the chapel and it was indeed the house in the photo called Bryn Hyfryd though I don't know what the name was when it was a chapel. The names of my Great Grandparents were indeed John and Anne Harris who lived at Bryn Hyfryd until they died I think (around 1948 and 1956) but I don't know where they lived before they moved there.
Also some more info on the Edwards family taken from a photocopied page that my mum was given by Chris Draper the historian - unfortunately I don't know the name of the book.
A John Edwards was leased land in Pant Uchaf by Mostyn Estates in 1859. John Edwards - a stonemason - was the son of Henry and Catherine Edwards and was born in 1833 at old Pen Y Ffordd farm cottage which was occupied by his parents from 1829 to 1834. The 1861 census shows that John Edwards and his wife (also a Catherine b.Llangwstenin 1832) lived at Pant Uchaf with their three children (another) John b.Llangwstenin 1853, (another) Catherine b.1855 and (another!) Henry b.1861.
As the two youngest children were born in Llandudno it could be assumed that the family moved to Pant Y Wennol between 1853 and 1855. There is a possibility that John Edwards and a Thomas Hughes from Mount Pleasant (who also leased the land from Mostyn Estates) may have between them built Pant Uchaf Cottage. By 1868 John Edwards had left Pant Uchaf and the cottage was occupied by Thomas Hughes younger brother Hugh, his wife Margaret and their three children.
In 1948 the tenancy of the cottage was taken over by Ann Hindley (nee Harris - my Great Aunt) and her husband Norman who later moved to No.2 cottage Lower Pant Y Wennol. The tenancy of the cottage then passed to Thomas George Harris and his wife Laura (my grandparents) and their daughter (my mum) until 1960.
So there is a possibility that as my family definitely did occupy the cottage from 1948 until 1960 and also Bryn Hyfryd, the John Edwards family may have been the Edwards I'm looking for. Annie could be the daughter of John or Henry (Jnrs). I'm finding it quite exhausting trawling through the internet and don't think I've quite got the hang of looking through the census records. I'm sure the nice people at the library will put me in the right direction.
If anyone has any idea how I can get copies of Kenneth Dibbles books about Penrhynside and the area(there are three I think) I would be most grateful. I have heard he lives in the area and may be able to sell me copies. One is called 'Penrhynside'. There does seem to be an address for him on this page:
