The area is part of the
Cantref of Gorfynydd, historically part of the
kingdom of Glamorgan. John le Fleming is said to have gained the manors of St. George, Wenvoe, Flemingston, and Llanmaes. Fleming was married to Amicia, daughter of Baldwin Magnus, Lord of Whitney. Fleming gave the manors of Flemingston and Constantine Walles to a younger son. In 1317, Flemingston was held by Philip le Fleming. It continued in his descendants until, on failure of issue male, William Fleming sold the estate to Lewis Thomas of Bettws; while an alternate account states that the le Fleming line ended in an heiress, who married a Thomas, of Llanfihangel, through whom a sale of the property was made to the Wyndhams of Dunraven. In 1801, the population amounted to 66 residents.
A Topographical Dictionary of The Dominion of Wales (1811) by
Nicholas Carlisle described Flemingston as belonging to what is now called the Hundred of Cowbridge, within the County of Glamorgan. Thomas Wyndham was the patron of the
rectory, and the village church was dedicated to
St. Michael. The
John Marius Wilson's
Imperial Gazetteer of England and Wales (1870–72) states that the Flemingston parish was within the
Bridgend district or Glamorgan. The population included approximately 63 residents, and there were ten houses. Flemingston was described as being one estate, the
manor belonging to Sir John Fleming, one of the twelve knights who came in with Fitzhamon in the time of
William Rufus. The rectory, part of the
diocese of Llandaff had a patron, the
Earl of Dunraven. ==Politics and Administration==
