Viscount Dillon
Harold Dillon,
17th Viscount Dillon.

Viscount Dillon, of Costello-Gallen in the County of Mayo, is a title in the Peerage of Ireland. It was created in 1622 for Theobald Dillon, Lord President of Connaught. The Dillons were an Hiberno-Norman landlord family from the 13th century in a part of County Westmeath was called 'Dillon's Country'. His great-grandson, the seventh Viscount, was a supporter of the Catholic King James II of England and was outlawed after the Glorious Revolution. He founded 'Dillon's Regiment' of the Irish Brigade in the French Army, which was supported by the Wild Geese and achieved success at Fontenoy in 1745.

However, his son, the eighth Viscount, managed to obtain a reversal of the outlawry in 1694 and later served as Lord Lieutenant of County Roscommon. His nephew, the tenth Viscount, was given the French title of Count Dillon in 1711 and was also created "Earl of Dillon" by James Francis Edward Stuart, the Jacobite claimant to the throne. His younger brother, the twelfth Viscount, was a Colonel in the French Army, but Dillon's Regiment was disbanded in 1793 due to the turmoils of the French Revolution.

His son, the twelfth Viscount, notably represented Westbury in Parliament and conformed to Anglicanism in 1767. His son, the thirteenth Viscount, sat as a Member of Parliament for Harwich and County Mayo. His great-grandson, the nineteenth Viscount, was a Brigadier in the Army. As of 2010 the viscountcy and French earldom are held by the latter's great-grandson, the twenty-second Viscount, who succeeded his father in 1982.

In France

Being of foreign origin, the Dillons needed to be "reconnus nobles en France" as "noblesse d'origine etrangere" and "maintenus nobles". They were "maintenus nobles" in 1759.

What's more, they were acknowledged as being of "extraction chevaleresque" (very old nobility), having been noble since 1347, and so allowed to the "Honneurs de la Cour" by the King of France in 1750, 1769, 1770, 1775, 1777, 1785 and 1788.

So they are very near the top of French nobility, since for the title of Duke, titles mean nothing in France.
