House of Detola
From Tardis Wiki, the free Doctor Who reference
The House of Ditola was the imperial family of the Great Kingdom of Jokastarna in Ecto-Space. Which generation of the House was currently on the throne was mentioned in the formal way of phrasing a date on the planet.
Empress Helena was a member of the 14th generation of the House of Ditola, and her descendant Emperor Lukor was a member of the 17th generation. (AUDIO: The Choice)
