This is a case of putting two and two together and possibly getting five . . .
On the OS map for 1899, and only on this one map, there is a Gethin Villa marked, situated almost exactly where Lledr Hall is today. It is not he same house, Lledr Hall as it exists now was built in the early 1900s. Other than the map, I can find NO other mention anywhere of a Gethin Villa.
However, and this is the second half of my equation. A famous judge of the late Victorian era, Sir Thomas Townsend Bucknill had a shooting lodge in Dolwyddelan for at least 20 years.
November 3rd 1899 . . .
There is lots to read about Bucknill on the internet, he was quite famous through trying some high profile murder cases in the early 1900s, though no mention of a connection to Dolwyddelan after 1902. Could his shooting lodge have been Gethin Villa, I will find out one day !
