What are the limitations of the Surname DNA test?
• i) The Surname DNA test looks specifically at the Y-chromosome and thus will tell you about your direct paternal line – information about other lineages cannot be provided using this test. • ii) The results need someone to compare with. This is usually a putative cousin. It wouldn’t be able to predict your surname just from the results. In the case of adoptees, prior knowledge in the form of a suspected or lineage would be needed first. • iii) Females cannot undertake a Surname DNA test.
