Biogeographical Evidence for the Iberian Origins of R1b-L278 via Haplotype Aggregation (2014)

Abstract

The status on the roots of haplogroup R1b remains split between an Iberian origin prior to the Last Glacial Maximum (LGM) and a West Asian origin coinciding with the Neolithic expansion. Existing methods generalize geographic patterns based on large population genetic frequency and diversity.  Haplotype Aggregation delivers a coherent genetic record selection and Biogeographical Multilateration (BGM) illustrates directional flow as well as chronological and physical origins at the haplogroup level.  The resulting phylogenetic relationships across multiple high level branches of R1b support an Iberian origin and a rapid Western Atlantic migration.

Biogeographical Origins and Y-chromosome Signature for the House of Normandy (2014)

Abstract

A sixty-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. This suggests that such phylogenetic prevalence is a biological record, supports the reliability of early genealogies for Rollo ‘The Dane’ and the House of Normandy. Current Y-chromosome haplogroup maps only cover the broadest-brush strokes of the highest-level origins.  Existing methods only generalize geographic patterns based on large population genetic frequency and SNP. Biogeographical Multilateration (BGM) illustrates the paternal ancestor migration flow as well as Rollo’s chronological and physical origins at the individual haplotype level.

Y-Chromosome Haplotype Origins via Biogeographical Multilateration (2014)

Abstract

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.

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

Abstract

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.
