Cosette is 2nd cousins with Regulus and Sirius. Her friend group consists of Regulus, Evan, Barty, Rosette, Juliette, and herself. The girls met on the train ride to Hogwarts and have been inseperable ever since. The girls in her friend group is commonly called 'The Ettes', fondly by the males in her friend group and other Slytherins, but it was more bitter from outsiders. The nickname was assigned to them when they were in first year, sorted minutes beforehand, by Narcissa Black, a 7th year, when she first saw The Ettes she saw a bit of herself in each of them and then almost imediately took them under her wing, and when she realised all there names had the same ending, well, the nickname seemed natural.
