Gabrielle Murray-Harker
From Absit Omen Lexicon
Gabrielle Murray is the sole child of Mina Murray & Vlad Dragulia. She formerly had kept Murray-Harker as her last name until she dropped the Harker surname upon her return to the Ministry after a sabbatical in the summer of 2009.
She resides as the Dept. Head for the Int'l Magical Cooperation and a Wizengamot member within the Minisry as well as a staunch supporter of excellent magical education.
She has been known to have had many suitors since her Hogwarts days, but it seems an old flame has reclaimed her heart and so, that's sure to be an interesting twist in the road.
