Tingo was a member of the Gonfelin Thieves. He is the brother of Gobbo, Bumbo, and Spingo, the uncle of Andio, the son of Nokko, brother-in-law of Bisky, possibly related to Samolus Fixa, and a distant descendant of Gonff the Mousethief, Columbine, Gonff II, Abbess Bryony, and Dandin. He was involved in an ownership dispute with Gobbo over a sandbag (which he won), and attempted to attack Bisky until Nokko stopped him.
Tingo was a minor character, so not much else is known.
