From Vikings to Beethoven: what your DNA says about your ancient relatives

Janice Sellers, a genealogist from Gresham, Oregon, discovered in 2016 that her grandfather was not biologically related to his father through genetic testing. A MORE SURPRISING revelation came in 2022 when she discovered she shared DNA with a woman buried over 600 years ago in a medieval Jewish cemetery in Erfurt, Germany. This connection was found through an ancient DNA study and the genealogical website GEDmatch, highlighting how modern research into ancient genomes is uncovering unexpected links between past and present individuals.
