- "This is my great-grandfather, Mam."
- ―Tumen to the crew of the Barnacle
Mam was the great-grandfather of Tumen. He lived in a village in Yucatán with Kan, K'ay, and Chila. Jack Sparrow and his crew met Mam and his family when they visited Yucatán. Later when the Sun-and-stars amulet was stolen he grew very sick. But when Jack and his crew returned it he was better.
