The Trinket Family is one of the 13 Patriarch Families of the Capitol. They are one of the most notable families there, since one of them plays a major role in the trilogy of the Hunger Games series. Its also pretty well known in Capitol Couture too. Some of these members are escorts. Traditionally, the Trinkets run a very succesful bank in the Capitol, and two of the members that are noted are Effie's parents.
Sometime during his 30's, Drusus Trinket married into Panems presidential family by marrying president Coremus Snow's son Calemus Snow. Drusius had a brother called Janus who attended the wedding as a best man, even he was young. Janus had a son named Jerome, who had a son name Justinus Trinket.
Justinus and his wife Euphemia Trinket were a famous couple back in their day as they were not only bankers but also sponsors and investors of Capitol News. Justinus and Euphemia had a daughter also named Euphemia, but called her Effie for short.
