Tanselle is an unseen character in Game of Thrones. She is long dead by the time the series begins.
In the books
Tanselle was tall and slim, with small breasts. Her hair was black and her skin tone resembled the color of olives. Due to her height, she was nicknamed "Tanselle Too-Tall".
Tanselle was a puppeteer whom Dunk gained an instant attraction to upon meeting her at the tourney at Ashford, at which he also befriended Egg, the boy who would grow up to become King Aegon V Targaryen. Dunk asked her to paint his shield after seeing her puppet show. While performing a skit in which the hero kills a dragon, she was attacked and insulted and had one of her fingers broken by Prince Aerion Targaryen, who took the dragon's death as a slight against House Targaryen and accused her of treason. Dunk came to her rescue, but was taken prisoner for striking one of the royal princes. Tanselle and her family left for Dorne as quickly as possible afterwards, but she left behind Dunk's painted shield.
At some point between the ending of The Hedge Knight and the start of The Sworn Sword, Dunk and Egg reached Prince's Pass and later Vaith in Dorne. They did not find her, and Dunk gave up hope that they would. Her fate after this is unknown.
Tanselle would hence appear in any potential TV adaptation of The Hedge Knight.
