Y-chromosome SNPs in the historical era: discovering cascading hierarchies of SNPs
Until recently, Y-chromosome SNPs were regarded as only useful for ancient ancestry. This presentation will look at the increasing importance of SNPs for genealogy in the historical era, giving examples of branch markers which can now identify male line descendants of family lineages established between the 13th and 16th centuries. Some proposals will be put forward for a methodology to advance the discovery of SNPs from this and even more recent periods. As the boundary of SNP discovery moves closer in time, more and more people will have the chance to use DNA testing to link themselves to major branches of families and even named historical individuals.
After long experience as a librarian, Graham began teaching family history as a tutor of evening classes at the University of Strathclyde. He has been a tutor on the University’s Postgraduate Programme in Genealogical Studies since it commenced in 2007 and is now Principal Tutor. He is author of Discover your Scottish ancestry (2nd ed. 2009) and has an interest in genetic genealogy research, leading the Battle of Bannockburn Family History Project, with a focus on tracing early descents using documentary and genetic evidence. He is keen to promote the importance of using male line descendants with reliable documentary evidence as reference points around which genetic groupings can be built.
