Jingatheen family

The Jingatheen family were a family of Raxacoricofallapatorians. One member of the family was the adopted Margaret Ag-Kris Therur-Ford Jingatheen. (COMIC: A Confusion of Angels) Originally known as Blon Fel-Fotch Passameer-Day Slitheen, the former Slitheen had been regressed back to an egg after looking into the Heart of the TARDIS, with the Ninth Doctor intending to take her home to Raxacoricofallapatorius, where she would have a second chance at life.

Behind the scenes
An early draft of The Stolen Earth had the Tenth Doctor and Donna Noble encountering an infant Blon Fel-Fotch Passameer-Day Slitheen at the Shadow Proclamation. She was adopted by the Jingatheen family, who expressed their distress at the disappearance of their twin planet Clom, and named Margaret. (REF: The Writer's Tale)
