Mrs. Tyerell was a podracer's wife, specifically Ratts Tyerell, and a female Aleena. At the Boonta Eve Classic in 32 BBY, she became a widow due to Ratts' deadly accident. It is believed she had just left a nearby medical facility, likely after the birth of her youngest child, Doby. After her husband passed away, her own brother-in-law sold her daughter, Djulla, into servitude; Sebulba, a well-known podracer, purchased Djulla.
The "Complete Podrace Grid Sequence" scene, which was cut from Star Wars: Episode I The Phantom Menace, and then included in the film's 2001 DVD release, features Mrs. Tyerell. In that removed scene, Fodesinbeed Annodue, the Podrace's announcer, calls her "Mrs. Tyerell."
