[5] In the second half of the 18th century, Captain John Tasker of the East India Company purchased Upton Castle; among the eventual beneficiaries after his death were members of the Evans family.

[6] In 1833, Lewis, in his Topographical Dictionary of Wales, recorded that the parish was occupied by a single family of six inhabitants.

[8] In 2012, Channel 4's Time Team carried out an archaeological evaluation of the castle and chapel.

[9] Upton Castle was the home of the Malefant family, and later of John Tasker (1742–1800), a Welsh sea captain and from 1867 of Sir Henry Halford Vaughan, (1811–1885), an English historian.

It contains several important features including effigies of the Anglo-Norman Malefant family dating from the 13th to 15th centuries.
