Title: Using SNP Testing & STRs to enhance a genetic genealogy research project. (excellent audio)

Genealogists using DNA testing have become familiar with the STR tests on the Y chromosome, but may be less comfortable with SNP (point mutation) testing. This talk will review the three main types of SNP test available to the family history researcher – sequence testing, like the Big Y; individual SNP testing; and SNP panel tests – and which is best for which kind of question. We will discuss how using SNPs in tandem with STRs enhances the power of both, using examples from recent research into surnames and older ancestral lineages. We will also consider the limits to SNP-based research, and how using them may develop in the future.

John Cleary, university lecturer and Cromwell's Scottish prisoner tracing project coordinator: John is a lecturer at a university in Edinburgh and a member of ISOGG (International Society of Genetic Genealogy). He gives talks on using DNA in family history research in Scotland, and is interested in how genetic genealogy can help to understand the origins and spread of surnames. He is involved in a project researching the fate of Scottish prisoners captured by Cromwell in the Civil War and transported to the Americas, working with the Prisoners’ descendants using DNA and genealogy to discover more about their fate.

These lectures were sponsored by FTDNA (FamilyTreeDNA) and organised by volunteers from ISOGG (International Society of Genetic Genealogy).
