I have been there as I remember the red tiles.
I have been looking at John Jones following the information posted by AJ. This will take a while to research due to having such a common name.
On the 1911 census he states that he has been married less than one year. His wife is Annie, age 24, born Trefriw. The only marriage I can find which looks likely is in the June quarter of 1910 registered in Conwy District. John Jones married Annie Ellen Williams. Reference is Vol 11b, page 745. It would be worthwhile getting their marriage certificate as that would show the name and occupation of his father.
I found a possible person for him in the 1901 census. He is a servant in the household of John Calvin Jones in Maenan. John Calvin Jones is a farmer living in Maesygroes. It shows John Jones, servant, age 20, Carter, born Roewen. It is Llanwrst district, schedule 8, piece 5242, folio 87, page 2.
There doesn't appear to be a John Jones born Rowen in the 1891 census. I have tried to find him in this as he should be with his parents but he has eluded me to date. There is a John Jones age 8 living with his parents in Maenan. This states he was born in Maenan. His father is Robert Jones, age 31, farm labourer born Maenan.
One thing that intrigues me is that on the 1911 census Lydia Evans is shown as his sister, she is single. Why is her surname Evans? I have tried searching for her as her name is not so common but this has drawn a blank up to now. The only birth registration that comes up is for Lydia Evans born 1891 and registered in Wrexham RD.
I shall continue my search.
