7. Ryan – the little kings

The meaning of the Irish name Ryan comes from the old Gaelic word "righ" and the old Irish diminutive of "an," which together form the meaning of "little king."

The name Ryan comes from the Irish name O' Riain - a contraction of the older Irish form O'Mulriain, which is now virtually extinct.

Ryan is also an extremely popular first name, especially in Britain and the U.S.

The Ryan family motto is 'Malo More Quam Foedari', which, when translated, means 'I would Rather Die than be Disgraced'. And they call them “little” kings…

8. O'Connor – patrons of warriors

They might not be warriors themselves, but at least O’Connors descend from them!

The O'Connor name, with its varied spellings, doesn't spring from a common source. The name arose in five areas of Ireland: Connacht, Kerry, Derry, Offaly and Clare and split into six distinct septs.

The most prominent sept is that of the Connacht O'Connors who gave us the last two High-Kings of Ireland: Turlough O'Connor (1088-1156) and Roderick O'Connor (1116-1198). They trace their heritage and name from the Irish "Ua Conchobhair," meaning from Conchobhar, a king of Connacht.

9. O'Neill – from a champion, Niall of the Nine Hostages

The O'Neill family traces its history back to 360 A.D. to the legendary warrior king of Ireland, Niall of the Nine Hostages, who is said to have been responsible for bringing St. Patrick to Ireland.

Niall is also said to have been incredibly fertile – he has 3 million descendents worldwide.

“O’Neill” is derived from two separate Gaelic words, "Ua Niall," which means grandson of Niall, and "Neill" meaning "champion."

Ireland’s O'Neills were known by the nickname "Creagh," which comes from the Gaelic word "craobh" meaning branch, because they were known to camouflage themselves to resemble the forest when fighting the Norsemen. Crafty fellows, those O’Neills.
