Here's a bit of history ... you can see Tir Stent about a km to the right of Tyddyn Ednyfed.....
Ellis Morris (d. 1693) of Dolgun-uchaf appears among the list of freeholders entitled to graze cattle on Tir Stent in 1654 (Smith & Suggett, 1995). On the 1838 tithe map 'Tir y Stent' is shown as an undefined large area within this character area, but seemingly without owner or tenant, implying common land. The area has a typical scattered settlement pattern, with farms concentrated on the lower slopes, and all that are shown (including Tyddyn Ednyfed, Trefla (Trefeilia), Hafodlas, Pen yr Allt and Drefgerrig) still exist today (without recent additions). Again, the large enclosures shown on the tithe map show the extent of holdings rather than individual fields. The infrastructure of trackways and roads in this area is quite complex (particularly when compared with neighbouring areas), and all routes are still traceable today.
So... after that little microscopic excursion into Deepest Wales, let's listen to Anelog and "Melynllyn"
