About the O'Byrne Surname

Many O'Byrne families will find their roots under Byrne, the form most records use.

The O' in front of the name is a particle that was often added to Byrne on registers. Regional accents shaped spellings long before dictionaries fixed them.

Heraldry is personal: arms associated with the Byrne surname were borne by specific families, and sharing the name does not mean sharing the blazon. Want more than a summary? See the O'Byrne family name pack.
