This is the name of the house my great grandfather (built ?) in Clydach.
Roughly, translated it means:
Ford (of) the wine.
 He had decided to name it so, after a house he had known in his youth (apparently). My sister and I searched 'far and wide', to locate any evidence of this mysterious domicile which had captured this reminiscence of his but, to no avail.
I was doing some research earlier and, as I do, began to let my thoughts wander (still hovering, around the subject I had been imersed in) but venturing along a different, tangent.
This 'tangent', jogged my memory into wondering if, the location of this house name, could hold any evidence of its whereabouts . . .
I was sort of, lucky - I found a description of the mental anguish a 'T. Thomas' had been enduring while changing his faith to Unitarianism, he left this quote (which I believe to be in 'Yr Morfynydd', a Unitarian pamphlet of 1897 pages 284-8). He says:
"Undodiaeth yn Ystrad a Rhydygwin"
Translated, it means:
For Unitarianism, I go along the crooked vale to Rhydygwin.
So in an area, close to his family roots in Llanfihangel Ystrad, there had been a house/Unitarian chapel of that name! . . . at least I have something to work on now!!!
Yay!!!
