Irish Names

Some of the most popular surnames in Ireland have histories that go back hundreds, even thousands of years. Several originated from the ancient Irish clans that ruled various parts of the country over the centuries.

Foley Celtic art. Image Copyright - Ireland CallingMany have a prefix of either ‘Mac’ or ‘O’. Names with a prefix of ‘Mac’ means ‘son of’ while the ‘O’ prefix’ means ‘grandson of’ or ‘descendent of’. For example, a person with the surname O’Neill would be a descendent of Neill – or most likely Niall of the Nine Hostages.

Most names have several variations in spelling. This is because for centuries the names existed solely as spoken words, there was no reason to figure out any particular spelling. When names needed to be written down for tax records, there were often numerous interpretations of the spellings. In some cases the interpretations were so different that two surnames from the same family line could appear to be totally unrelated.

Names became Anglicised

After the Cromwellian invasion of the 16th century, many people in Ireland dropped the prefixes as it became extremely difficult to find work if you had an Irish sounding name under British rule. Dropping the prefix and altering the spelling to a more intuitive English language spelling is how many of the old Irish names continued to develop into what they are today.

Following the 1798 Rebellion, there was a surge of patriotism among the Irish and many families reinstated the ‘Mac’ or ‘O’ prefixes to assert their national pride.
