In his book "Saxons, Vikings, and Celts: The Genetic Roots of Britain and Ireland," author Bryan Sykes argues that oral myths provide insights into genetic heritage that may be more reliable than the sometimes unclear findings of archaeological research. He suggests that these stories passed down through generations carry valuable information about the ancestry and migratory patterns of ancient populations.

Sykes emphasizes the importance of understanding cultural narratives and traditions, as they can reveal connections to historical events and lineages. By focusing on these oral traditions, he believes that we can better comprehend the genetic landscape of Britain and Ireland, highlighting the value of non-scientific sources in enhancing our understanding of human history.
