The Quinn family is one of the three most influential noble families in the Kingdom of Dawn. The main branch is made up of Horford Quinn, the former Prime Minister; Andrea, his witch daughter who was forced to leave the family when she was awoken as a witch at 16 years of age; Hawn, his adopted son from a different branch of the family, and Horford's late wife Fenancy, who died of a disease a year after Andrea's leaving.
The Quinn family had served the Moya royal family for hundreds of years, along with the other two big noble families who swore loyalty to the royalty, until Andrea told them that King Roland asked them to rebel against Moya Appen. With the help from Roland , and the support of the other two noble families, Earl Quinn overthrew the Moya family and declared himself the king of the Kingdom of Dawn, making Quinn family the royal family. However, in reality, Roland was the one who had the real power.
Apart from Andrea, the family made their first appearance starting from Chapter 932.
