I was interested in this as it covers the area my relatives the Roberts' lived. The Tyn Yr Yrn is the address given on the marriage cert for Elias Roberts 1840. he was a labourer there. Thanks for posting the picture, I hadn't asked about this before so now I know where it is.
My vague memory and chat would have 5 Owens from there. 2 brothers and a sister who we thought stayed on at the farm. May well have things wrong butt he other suggestions are.
Owen Owen. Lived in Fault (I never can spell it), had a daughter Rhian who worked with my mother in Llandudno Hospital - not many years older than me.
Howell. Lived in Pydew. I can't remember the place but somewhere opposite side of the road of and before Maelgwyn. From Skerryvore, Past Eithinog sort of way on the right.
I think they both (and probably all of that generation) are RIP
