Prince of Coolavin

Prince of Coolavin was a title first applied by popular usage to Charles MacDermot, 1707–1758, then head of the MacDermot family of Moylurg. Coolavin () is a barony in south County Sligo in Ireland. Up to the late 16th century the head of the family were still Kings of Moylurg, but had lost their lands due to confiscation.

The adoption of the term indicated that the family considered themselves "princes", and also considered as such by their neighbours. The title continued to be used by the head of the family into the 21st century. Provided by Wikipedia
