A woman of unknown origin and identity abandoned her daughter after giving birth to her at approximately 2PM, leaving her baby on the doorstep of the church at Ruby Road on Christmas Eve 2004, slipping away into the night, while the Fifteenth Doctor stopped the Goblin King and his goblins from altering time and eating the baby before she could grow up to become Ruby Sunday.
After Davina McCall hosted Ruby Sunday on her programme in an attempt to find the families of "foundlings", she could find no trace of Ruby's mother. (TV: The Church on Ruby Road [+]Loading...["The Church on Ruby Road (TV story)"])
