A review was made of existing genetic genealogy findings that infer characteristics of the Y-DNA of members of the British Monarchy. Nine sustained Y-DNA lineages since the year 927 CE were noted as dynastic groups. Haplogroup and haplotype characteristics of three of the dynasties were presented with two more dynasties noted as testable but unpublished. Cultural and geographical origins of these dynasties were considered as context for their DNA haplogroups. Specimen candidates for further testing were identified noting that some will require Ancient DNA (aDNA) recovery and analysis.
