Hello, I don't know of a 'Lodge Uchaf', but There was a Ty Uchaf - meaning upper house. I don't remember seeing Lodge Uchaf on the ordnance Survey maps either. Our house, Ty Isaf was Lower House. Mrs Thomas lived in Ty Uchaf. I used to but my Christmas turkey from her. The name Ty Uchaf in speech gets shortened to Tuchaf - or even Tucha. Everyone called Mrs Thomas - Mrs Thomas Tycha - all one name. and we were Pook Tysa, or Pook Tisa, or just Tysa - as the house, built in 1642, was 'permanent', and we were transitory.
There was as well, Ty Canol - middle house. The houses were named according to their position on the hillside. These three must have been the earliest ones built.
By the way, the Mrs Thomas I used to buy my turkey from was not a young woman, and I don't remember if there were any sons (or daughters for that matter) however if there were sons, the farm might well be in the same name. Try the telephone directory.
Sincerely,
Rachel Bowen
Hope this helps.
