Delphini Atchley

Delphini Atchley (née Riddle) is an Irish Pure-Blood witch and youngest child of Tom and Nathalia Riddle. She attended the Durmstrang Institute with her older brother, Declan. She became a Death Eater when her father killed her mother in 1970. Delphini married Cato Atchley, a fellow Durmstrang student, in 1976, and gave birth to her son, Salem, in 1980. Her niece, Signa, was born shortly after. Her father was killed by Harry Potter, in 1981, which was when Delphini decided to settle down and raise her son.

She attempted to murder her sister-in-law, Juniper Riddle, in 1987, for trying to become a muggle-born Death Eater. Juniper was killed by Declan in 1991, which sparked joy in the Atchley Family. She was imprisoned in Azkaban in 1998, for multiple murders.
