Pre-nineteenth century the area was sparsely populated owing to the agricultural land being poor of quality. The best land was found to be along the banks of the River Loughor where two properties of notable character stood. The first is Plas Mawr also known Plas Llanedy and Cwrt y Ceidrim. The main portion of the house dates from the 16th century. This was the seat of the Penry family and their descendants, Jones. William Penry and his son Henry were High Sheriffs in 1736 and 1756 respectively. The Penry family descended from Bleddyn ap Maenarch and were at Cwrt y Ceidrim in the Elizabethan era. In 1876 Plas Mawr Estate nearly was offered for sale. Later the Buckley family acquired it and in 1921 they offered for sale the freehold farm .
