Yanas Tigan was a Trill and the mother of Janel, Ezri and Norvo. She owned the sixth largest pergium mine in the Sappora system. Yanas did not have a good relationship with Ezri, her only daughter and this relationship deteriorated even further when Ezri was joined with the Dax symbiont. With the memories of eight other people, Ezri found it difficult to distinguishe herself from the others. After she arrived home after being joined, she presented herself to Yanas as Curzon. Yanas also tried to discourage her youngest son, Norvo, from drawing, instead she wanted him to work for the company. After it was revealed that her two sons had been involved with the Orion Syndicate and Norvo had killed Morica Bilby, Yanas realised she was to blame. (DS9: Prodigal Daughter)
