Frontiers in Genealogy and Heraldry - International congress for genealogical and heraldic Sciences edition:30 location:Maastricht date:24-28 September 2012
Today, genetics is a popular additional tool for genealogy: a discipline called genetic genealogy. In this presentation, I will discuss all basic principles and applications of genetics which are valuable for genealogy. Genetic genealogy is useful for recreationists to verify their paternal and maternal lineages and to extend their lineages by using haploid markers in Y chromosome and mtDNA respectively. Especially the Y chromosome is important for genealogy because the biological paternal lineage is not always the same as the juridical patriline due to non-paternity events. Next, genetic genealogy is also very useful to find a connection between families of a similar village or region with the same surname and between families with different spelling variants of a similar surname without any archival evidence of a relationship between the families. Moreover, if in-depth pedigree data of many individuals of a population are combined with haploid markers, it is even possible to disentangle signals of temporal differentiation within a population genetic structure during the last centuries. Several examples from a recent genetic genealogical study within Flanders will be used in this presentation to illustrate all applications. Nowadays, it is possible for genealogists and scientists to answer some relevant research questions which were impossible to answer without genetic genealogy. Nevertheless, more international cooperation between genealogical societies in the future will still enlarge the potential of genetic genealogy, especially for scientific research.
