The Kingdom of Dyfed (Welsh pronunciation: ['dəvɛd]), one of several Welsh petty kingdoms that emerged in 5th-century sub-Roman Britain in southwest Wales, was based on the former territory of the Demetae (modern Welsh Dyfed). The medieval Irish narrative, The Expulsion of the Déisi, attributing the kingdom's founding to Eochaid, son of Artchorp, being forced across the Irish sea, in the 5th century; his descendants founding the line of the kings of Dyfed, down to "Tualodor mac Rígin" (Tudor map Regin). The Normans invaded Wales (1067 to 1100), and by 1138 incorporated Dyfed into a new shire called Pembrokeshire after the Norman castle built in the Cantref of Penfro and under the rule of the Marcher Earl of Pembroke.

The Hundred of Dungleddy was a hundred in the centre of Pembrokeshire, Wales. It had its origins in the pre-Norman cantref of Deugleddyf. It derives its Welsh name from its position between the two branches of the River Cleddau (Cleddyf): the English form is a corruption of the Welsh. The area of the cantref was around 185 km2: it was the smallest of the seven cantrefi of Dyfed. The cantref was allegedly divided into two commotes. The Red Book of Hergest calls these "Castell Hu" (= modern Cas-wis or Wiston) and "Llan y Hadein" (=Llanhuadain or Llawhaden). These both appear to be post-Norman lordships and are not genuine native subdivisions. The western part of the hundred was English-speaking from the time of the Norman conquest, and formed part of Little England beyond Wales: the eastern part was part of the Lordship of the Bishop of St David's, and George Owen described it as bilingual. The three northeastern parishes of Llys y Fran, New Moat and Bletherston were Welsh-speaking during the 20th century. As their names imply, the civil headquarters of the commotes were at Wiston and Llawhaden, and the latter the cantref's ecclesiastical centre, perhaps the seat of a bishop during the Age of the Saints.Dungleddy was formalised as a hundred by the Laws in Wales Acts 1535-1542: a small part was transferred to the hundred of Dewisland, and various fragments of church land (Llandissilio, Llanfallteg, Llangan, Crinow, Henllan, Grondre and western Llawhaden) were acquired from Cantref Gwarthaf. The name continues in the present day as Daugleddau, a Church in Wales parish in the Diocese of St Davids, combining 13 former Anglican parishes of Pembrokeshire.

Penrhos Cottage is a very small cottage situated to the south east of Maenclochog. It was built as a ty un nos (house built in one night) around 1800, later rebuilt in stone, and last occupied in 1967. The typical North Pembrokeshire thatched cottage was once home to a family of 12, and is almost unchanged since the 19th century, having retained its original Welsh oak furniture. It is the last thatched cottage in Pembrokeshire.

Login is a hamlet in Carmarthenshire, Wales, in the Taf valley and sits on both sides of the meandering River Taf. A stone bridge crosses the river approximately 100 metres from a ford near the weir, which used to be the original crossing place. The postal address of Login covers a larger area than that bounded by the village signs. The district is called Cilymaenllwyd, and the main chapel for the region called Calfaria is located in the village. The region of Login consists of streams and valleys and hills, with a sparsely populated community. Cardi Bach ('little Cardi') was the local name given to the Whitland and Cardigan Railway that once ran alongside the River Taf between the towns of Whitland and Cardigan. The railway was closed in 1963 under the Beeching initiative. The Landsker Borderlands Trail, a public route for walkers, passes through Login. Some of the members of the Rebecca fraternity, active in the Rebecca Riots, were resident in Login. One of the hills is named "Radical Hill"; maybe this is in reference to the rebels, or perhaps it refers further back, to the stones deposited from the glaciers that once scoured this valley.The village is known for its wildlife: herons, kingfisher and otters are sometimes seen on the river. Red kites and owls occupy the air at different times of day and night, and several types of bats have been recorded at dusk and dawn.
