The following is an alphabetical directory of the SURNAME SEPTS and the most common anglicised VARIANTS of these septs. The information contained is as follows...
Surname in Bold, followed by variant spellings and anglicisations.
Sept name in Gaelic.
Clan and / or Tribal name from whence it descends.
Original location, placenames perpetuating the sept, and other major locations the name is now to be found.
A number of distinct septs can have the same anglicised surname, so these are seperately identified (not in any order of precedence).
Variant spellings are listed alphabetically referring to the surname in bold, and the same anglicised variant may be used for distinct septs, so this will direct you to other septs using this variant.
By noting the clan name of a sept you will find further information, such as references to the name over the past millennia, and the clan and tribal origins and genealogy of the clan, in PART 2., which has a page index to the clans, as well as family trees of the clans under their tribal name in each section.
