About us

A DNA surname project for Mannion and O'Mannion and genetic relatives. Participants with Mannion ancestry are encouraged to join the project. Variant spellings are also likely to be genetically related. For example Manning in County Galway that are genetically Mannion. At this time, those who have tested Y-DNA, mtDNA, X-DNA, and autosomal DNA should feel welcome. The best results for the surname study are expected to come from male Y-DNA Mannion participants.
