If you look on the Google map for Glanwydden at the T junction where the Queens Head Restaurant is, turn right down Waun Road then first left at Ffordd Wiga and down the lane on the right before the houses is Ainon Cemetery. You'll see the metal gate and kissing gate at the entrance.
I haven't yet located Maes but it isn't Tan Y Maes in Llandudno Junction. In the 1841 Census, the addresses from Esgyrun go along to Pydew in Bryn Pydew and I should know where Garth is because I've actually called there but I've had another senior moment!
The order then is Twll Llwynog (Fox Hole) then Maes then Ty Cefn (Back House)
In the 1851 index they have been collected in a different direction. Pen Y Bont is still there but I don't know the other names apart from Ty Newydd but again there are more than one Ty Newydd houses in the Parish.
I have a friend in Bryn Pydew who may know but if not the Archives should have the records and I'll visit there next week
