A Y-Chromosome Signature of Polygyny in Norman England (2013)

A thirty-seven marker short tandem repeat (STR) genetic analysis of Y-chromosomes reveals an unnoted modal haplotype showing a significant association with surnames claimed to have descended from the Norman dynasties and allied with William, Duke of Normandy, during his conquest of England. This suggests that such phylogenetic prevalence is a biological record, supports the reliability of early genealogies and illustrates the link between power and polygyny in European society.

Y-Chromosome Haplotype Origins via Biogeographical Multilateration (2014)

Current Y-chromosome migration maps only cover the broadest-brush strokes of the highest-level haplogroups. Existing methods generalize geographic patterns based on large population genetic frequency and diversity. New tools are required to illuminate our nomadic, stationary and genealogical histories. Biogeographical Multilateration (BGM) illustrates directional flow as well as chronological and physical origins at the individual haplotype level.
