Greengrass, Astoria (also given as Asteria)
(b. circa 1982)

Astoria is the younger sister of Daphne. She entered Hogwarts two years after her sister and eventually married Draco Malfoy. Their only child was named Scorpius Hyperion Malfoy.

The spelling of Astoria/Asteria's name is in question because it was given as Astoria by Time Magazine, and as Asteria in the hand-drawn family tree shown in the ITV documentary and on Jo's website. Jo also pronounces it Astoria.
