Grandmum is Jason and Michelle's English grandmother.


A former photographer for the London Evening Times, Grandmum was born in the village of Torrance in Scotland. It was there that she honed her photographic skills by doing portraits of sheep. After meeting her husband-to-be at a darts championship, Grandmum married the little man.

They then moved to the Falkland Islands where they had many, many children. After she accidentally caused the Anglo-Argentine War of '82, with her hairstyle, Grandmum decided it'll be best to move to the United States.


Grandmum is a wise and caring woman who knows just what kind of advice to give to Jason and/or Michelle.
