Further to my previous reply, I have now been able to see Cadvan's autobiographical notes in Welsh (Eurgrawn 1917).
b.1 Oct.1846 on small farm Yr Allt,Llangadfan.
grandfather on mother's side Edward Ifan, son of Maes Garthbeibio ; grandmother Coed-cae Llanbrynmair ; after marr.lived at Bron Haul,Garthbeibio.
grandfather on father's side David Davies,joiner,built Melin y Graig (Mill) on banks of River Twrch. He died young leaving his widow Dorothy with 6 children. Cadvan's father also apprenticed as joiner and in 1845 took a lease on some mountain land in Llangadfan and built a house, granary etc.
Cadvan m. 1st Maggie Jones, dau. of Hugh Jones,Ty'nypwll,Dinas Mawddwy,23 Aug.1876 in the Independent Chapel,Dinas Mawddwy.
2nd Mary Ada Evans,dau.of Meschach Evans,Manchester House,Coedllai (Leeswood) on 15 Aug.1882 in Wesleyan Chapel Mold.
The curious feature is that, after writing of wife 1 and the two children, she suddenly disappears and wife 2 arrives. The denominational periodical carries no obituary for her, as one would normally expect. If I remember, I'll ask around.
