Hugh's brother, as well as his older son, is named Charles. Anyone know the first names of Hugh's two sisters?

Hugh himself has a long-standing connection to Save the Children - his sister, Susan Lassen, helped found our Long Island Volunteer Chapter, New York, and was a member of Save the Children’s Board of Trustees. Hugh's House co-star Lisa Edelstein, who plays Dr. Lisa Cuddy, is also a supporter.
