As of January 2015, the Gerontology Research Group (GRG) had validated the longevity claims of 59 German citizens who have become "supercentenarians", attaining or surpassing 110 years of age. 49 of these were German residents and 10 were emigrants. There are currently six Germans known to be alive over age 110. The oldest of them is Maria Aulenbacher, born 7 November 1909 in Hesse-Nassau, aged 113 years, 29 days and living in the United States. Augusta Holtz, an emigrant to the United States, remains the oldest German citizen whose age has been verified: she lived 115 years, 79 days, from 1871 to 1986.
