Jenny of Oldstones

Jenny of Oldstones is a character mentioned in Season 7.

Background
Jenny of Oldstones was a poor smallfolk woman from The Riverlands. Prince Duncan Targaryen, who was Prince of Dragonstone at that point in time, fell in love with her and married her without his father, Aegon V Targaryen's permission. In order to keep her as his wife, Duncan renounced his birthright to the Iron Throne, a deed which inspired countless songs across Westeros. Eventually, Jenny was accepted at the Targaryen court. It is unknown if she died prior, during or after the Tragedy at Summerhall.

Season 7
At the Citadel, the Archmaesters mentioned Jenny, considering her a charlatan who claimed descent from the Children of the Forest.
