Ffynnon Iago Fach Farm.

[Deux Chevaux]

Does anyone recognise the name of the farm, and more importantly the whereabouts on the ground? I think it's somewhere around Parc Slip, probably to the north of The Fountain on the B4281 and south of Llangynwyd. I've been looking on Google and OS Maps with no luck.

EDIT I've just found Ffynnon Iago Fawr (Big) Farm, just need to locate Fach (Small) Farm now. Fawr was found about half a mile north of Margam Opencast Coal Mine, N/NE of Kenfig Hill.

On this map it is marked, very near Ffynnon Iago Fawr, slightly to its south:

Excellent detective work, thanks v.much. I hadn't thought to look on the NLS OS website, I'd been looking at modern OS maps.  I found what looks to be the ruin of the farmhouse on Google Street View so sad to see it no longer exists as a house.
