What is "muldoon"

Muldoon is an Irish family name. It is represented throughout the world where descendants of emigrants of people bearing that name have settled; e.g. USA, Canada, Australia, New Zealand, South Africa and other countries.

It is an anglicization of the Irish Ó Maoldúin, "descended from Maoldúin," which in turn was a legendary first name. This name means Hill-fort, the fort coming from the Duin part. This name Máel Dúin was first written down in the book of Lebor na hUidre or the book of Dun Cow. Máel Dúin is thought to be one of the first Irish explorers of the west coast of Scotland, he is thought to have established the first territory of Dál Riata west coast of Scotland. Also another Máel Dúin was one of the Kings from Mag Rath in Dál Riata, Western Scotland (See, List of the kings of Dál Riata), his name was Máel Dúin mac Conaill Died c. 689.

According to The Surnames of Ireland by Edward MacLysaght, there are three distinct septs of Muldoon: Galway (around Uí Maine), Clare (whose names were generally Anglicised to Malone), and in Co. Fermanagh where the name is most common.

The family logo is Pro Fide Et Patria, Latin for "For Faith And Country."
