Historical Origins of the O'Donoghues

There are fifteen recognised Ó Donnchadha tribes and septs listed below. Subscribing members can access considerable detail on the historical background to each of these tribes by clicking on these links.

Irish history and mythology is some of the best recorded in the world. Because of the work of the Irish annalists and genealogists we are able to identify where our ancient forebears may have come from. Also we are told what their tribal names are and the names of the septs that developed from those tribes. MacLysaght describes a sept as 'a collective term describing a group of persons, who, or whose immediate and known ancestors, bore a common surname and inhabited the same locality'. This is not the same as a Scottish clan, which were differently constituted, although the word 'clan' does tend to be used synonymously with an Irish sept.

In these pages the Irish spellings are used. Ó means basically 'from' but in genealogical terms means 'grandson or descendant of'. Uí is the genitive singular and so Donnchadh Uí Láegairi means Donogh of the O'Leary tribe/sept or descendants of Leary. Ua is the genitive plural and therefore Ua Donnchadha means in its simplest 'of the Donoghues'. Sometimes one sees this as Hua Donnchadha. One finds a great variety of spellings in the old Irish records, and I have stuck with those in my book 'Heroic Landscapes: Irish Myth & Legend'.

We continue to undertake historical research to generate new information, and combined with the Y-DNA project, this will lead potentially to a continuing expanded understanding of the ancient roots of our name and our families.
