Hi John, Maggie is quite right in that Ochoryfoel is in Nebo which is a tiny hamlet South of Llanllyfni, again South of Penygroes in the old county of Caernarvonshire. It looks like a transcription error as there is also a Llanfyllin but this is near Oswestry on the Welsh borders. As far as I am aware there is no Llanllyfin. Ochoryfoel means roughly 'side of the hill'. Arfor (Criccieth, North Wales)
