Lord Percival Tubbs was husband to Lady Tubbs. Together they lived in Croxton Hall. Their wedding was attended by the Tenth Doctor, who frequently attended their annual wedding anniversary parties.

Lord Tubbs was a horologist (a collector of clocks) and had built up an impressive collection, which he stored in the Clock Room of the house on the ground floor. Events surrounding the attempted theft of the Ancient Horologe (a wedding gift from the Doctor) caused one of their parties to be cancelled when, as a result of the attempted theft, the Horologe was broken and those nearest it were trapped in a different time. When the Doctor repaired the clock, all members of Lord Tubbs' household were returned to their proper time and the thief was safely apprehended. (COMIC: 13 O'Clock)
