Here are all the results with descriptions
O'Conor
Through war and politics, all the possible results of this test were considered the most powerful clans, dubbed Irish-Gaelic royalty. The O'Conor family are the historic Kings of Connacht, and last High Kings of Ireland. They trace back to the fifth century and contributed to Irish society in art, history, language, politics, and diplomacy.
O'Brien
Through war and politics, all the possible results of this test were considered the most powerful clans, dubbed Irish-Gaelic royalty. The O'Brien family are a royal and noble house founded in the tenth century. Their power declined two centuries later, after their territory shrank. They'd hold it for a little under five more centuries. Despite the turmoil, four O'Brien's ruled.
O'Neil
Through war and politics, all the possible results of this test were considered the most powerful clans, dubbed Irish-Gaelic royalty. The O'Neil family have held prominent positions in and out of Ireland. They're probably in the top three of famous, powerful Irish clans. They have ancestors like King of Ailech of the Early Middle Ages. After their land was merged with the Kingdom of Ireland, they became involved in major events, like the Irish Rebellion of 1641 and the Irish Confederate Wars.
Kavanagh
Through war and politics, all the possible results of this test were considered the most powerful clans, dubbed Irish-Gaelic royalty. The Kavanagh name is a famous one, and certainly a proudly old one. It dates to before the tenth century and comes from the old Gaelic word for 'born handsome.' They've fought off invaders and helped in politics since the nineteenth century. Ironically enough, however, finding information on them is more difficult than other clans.
