Lucretia was very beautiful with long auburn hair and dark smokey eyes. She was very thin.
Lucretia was a vain woman that didn't care much for her family. Her brother once joked she only married Ignatius because she needed someone to tell her how pretty she was. She was also smart and gifted at Arithmancy.
She was born on her fathers 24th birthday and was definitely her fathers favourite child. She had a complicated relationship with her mother, due to Melania's high standards. She attended Hogwarts from 1936 to 1943, mid war. She married in 1955 and had no issue.
