Jennis Templeton was a noblewoman from House Templeton, companion to Queen Alysanne Targaryen, and later Lady of Uplands during the reign of King Jaehaerys I Targaryen.
Jennis Templeton was a companion to Queen Alysanne Targaryen on Dragonstone from 51 AC.
During the second wedding of King Jaehaerys and Queen Alysanne, Jennis helped to disrobe the king as part of the bedding ceremony.
During Alysanne's pregnancy with Princess Daenerys, she sent Jennis to hold women's courts in her place.
In 55 AC, Jennis married Lord Mullendore of Uplands as arranged by Alysanne. It was considered an exceptional match for her, and a triumph for the queen.
