Geo Map from Scientific Research

Geo-genetic triangulation, showing probable locations of Beethoven’s autosomal ancestors. Regional intensity per hexagon represents number of shared ancestors between Beethoven and modern FTDNA customers, with the following criteria: (1) IBD segments (n = 665) must be shared (triangulated) between at least three individuals to be genetically validated and (2) ancestor locations (n = 89) of matching individuals must occur within the same hexagon to be geographically validated. Areas of Western and Central Europe that were considered but lack any probable ancestors are shown in gray. See alsoMethods S1L–S1O.
