S.C. woman, oldest living U.S. citizen, dies at 114 A 114-year-old South Carolina woman who was the oldest living U.S. citizen has died. Two daughters say Mamie Rearden of Edgefield, who held the title as the oldest person in the country for about two weeks, died Wednesday at a hospital in Georgia. Sara Rearden of Burtonsville, Md., said Saturday that her mother broke her hip after a fall about three weeks ago. Robert Young of the Gerontology Research Group said Mamie Rearden's September 1898 birth was recorded in the 1900 U.S. Census. The group, which verifies age information for Guinness World Records, listed Rearden as the oldest living U.S. citizen after last month's passing of 115-year-old Dina Manfredini of Iowa. Rearden was more than a year younger than the world's oldest person, 115-year-old Jiroemon Kimura of Japan.
