The cause was cardiac arrest, said her daughter Georgia Deal.

Mrs. Deal volunteered at St. John Academy in McLean and McLean High School during her children’s education and was active with local Girls Scout and Boys Scout troops. She also volunteered with Meals on Wheels and numerous Catholic organizations, including the women’s council at St. John the Beloved Church in McLean.
