The history of the last name Dillane

The surname Dillane has its origins in Ireland, where it is a variant of the more common Irish surname Dillon. The name is derived from the Irish Gaelic "Diolún," which means "faithful" or "loyal." This suggests that the name was likely given to someone who was considered a loyal or trustworthy individual.

The Dillane surname is believed to have originated in County Westmeath, Ireland, where the Dillon clan was prominent. The earliest recorded spelling of the name appears to be "Dyllane" in the Fiants of the Tudor Sovereigns during the reign of Queen Elizabeth I in the late 16th century.

In the 16th and 17th centuries, the Dillane family was closely associated with the town of Kilbeggan in County Westmeath. One notable historical reference is the mention of Richard Dillane, a landowner in Kilbeggan, in the 1641 Depositions, which documented the Irish Rebellion of 1641.

In the 18th century, the Dillane family spread to other parts of Ireland, including County Cork. One prominent figure was Michael Dillane (1750-1825), a wealthy merchant and landowner from Cork. He was involved in the Irish Rebellion of 1798 and was later elected as a Member of Parliament for County Cork.

Another notable individual with the Dillane surname was John Dillane (1805-1865), an Irish nationalist and member of the Young Ireland movement. He was born in County Westmeath and played a role in the Irish Rebellion of 1848.
