Catherine Read was a Scottish artist. Born in the early 18th century, she is most known for her work as a portrait-painter. She was for some years a fashionable artist in London, working in oils, crayons, and miniature. From 1760 she exhibited almost annually with either the Incorporated Society of Artists, the Free Society of Artist, or the Royal Academy, sending chiefly portraits of ladies and children of the aristocracy, which she painted with much grace and refinement.

Sir John Wedderburn, 5th Baronet of Blackness, was a Perthshire gentleman who joined the 1745 rebellion of Charles Edward Stuart. He was captured at the Battle of Culloden, taken to London, and convicted of treason. He was hanged, his estates were forfeit to the Crown, and his family was attainted. The Blackness in his title is Blackness House in Dundee rather than Blackness in Lothian just west of Edinburgh. His son John Wedderburn of Ballindean fled after his father's death to Jamaica, where he re-established the family's fortunes via slave sugar, and eventually regained his father's title.
