The most common areas where it is still found today are in County Clare and County Galway in the Republic of Ireland. It was brought to these areas by an ancestor of the name, Teige O'Treacy, who was of a strong and powerful aristocracy and is believed to have come from the royal family of the O'Brien dynasty.

The name also has an association with County Limerick with the O'Treacy family being among the leading clans of that area during the medieval period and were renowned for their long-standing loyalty to the O'Brien dynasty. The name is still found in pockets of County Limerick today, alongside counties Kerry and Tipperary.

Besides Ireland, the O'Treacy name can now also be found in many countries around the world due to Irish emigration, from the USA and Australia, to the UK, Canada and New Zealand.
