Editors Note: David Austin Larkin (aka Dáithí Ólorcáin) of Queensland, Australia is a longtime researcher of Irish genealogy and has published a number of helpful and informative books on Irish genealogy based on an extensive review and compilation of the Irish annals and pedigrees. David summarized that work in 2007 with a compilation of thirty-two (32) pedigree charts of Irish clans and surnames which are re-published below.
Irish Surname Relationship to Clans
The surname directory from his work, “Irish Septs – Surnames, Variants, Tribes and Locations” provides a good link of modern surnames to the Clans and Septs identified from the Irish annals. See Irish Septs Vol 1 for more information.
