Theres a John 'Rich' Jones c1875, born PENAL, Merionthshire, boarding in the PontyPridd District in the 1901 census - didnt make a note of the Census ref - can you find it from that detail ?
Wondered if it linked to the 1902 Richard - did he survive till 1911 btw?
Couldnt see an obvious marriage to a Margaret tho
