The Declaration of Independence's Irish signatories officially signed the document on August 2 in 1776, a full month after US independence was declared on July 2.

This was several weeks after the final draft of the declaration had been approved by Congress on July 4, the day we normally associate with independence in the US and named Independence Day.

The Irish signatories of the physically beautiful Declaration of Independence made it all the more special and when I was a kid; I had an image of it on my wall. The eight Irish signatories of the Declaration of Independence, including "McKean," gave me the story I needed to feel at home here like a native. My love of country, the United States, and of my heritage, Irish, converge in that document because I acknowledge the Irish who risked their lives to sign it.

Among the citizens who signed what could have been a death warrant, were at least eight Irish Americans, three born in Ireland.

Many of them were Orange Irish or Scotch-Irish who hated monarchy, and whose spirit of independence is at the heart of the Republics they would crucially help found in America and Ireland. Their brand of Irish defiance saw right through British imperialism and used Enlightenment Republican ideas to create an alternative society for free people.

The Irish and Irish American signatories of the Declaration of Independence

Thomas McKean (March 19, 1734 – June 24, 1817) was the son of William McKean from County Antrim (Aontroim) who came to Pennsylvania via the city of Derry (Doire) as a child and later married Letitia Finney whose family had also emigrated from Ireland.

Thomas would become an American lawyer and politician, serving as President of Delaware, Chief Justice and then Governor of Pennsylvania. During the American Revolution, he was a delegate to the Continental Congress where he signed the United States Declaration of Independence and served as a President of Congress. Thomas McKean led the movement in Delaware for American independence and served as commander of a patriot militia group known as the Pennsylvania “Associators.”

Charles Carroll of Carrollton in Maryland (September 19, 1737 – November 14, 1832) was the only Catholic and the longest-lived signatory of the Declaration of Independence, dying at age 95.

He was held up by Catholic Americans as tangible proof of their patriotism and loyalty in America which was run by a largely WASP establishment until JFK's election. He is descended from the noble Gaelic family of Tipperary, Clan Ó Cearbhail who trace their origin to The Cianachta, a tribe recorded to the third century CE. He was born in 1737 in Maryland—the only colony tolerant of Catholic immigration, thanks to Lord Baltimore.

James Smith

James Smith was born in Ireland in c.1719 and was forced with his family to emigrate to the American colonies as a boy due to abuse by landlords. The name "Smith" in Ireland is oftentimes a translation of MacGabhann, which is an older Irish name meaning "son of Goibhniu," who was the Celtic deity of metallurgy.

Smith emerged as a leading lawyer of his day and wrote legal opinions denying the constitutional power of Great Britain over the colonies in America. He also urged as Jonathan Swift would do in Ireland, an end to the import of British goods.

He raised a militia group in York, PA and joined the American Continental Congress in July 1775, a year before the Declaration was ratified. Smith would become a member of the Continental Congress 1776-1778, and served in the War of Independence as a Colonel of Pennsylvania Militia 1775-1776. He was killed on July 11, 1806.

Matthew Thornton was born in Ireland in 1714 and went out to America as a four-year-old child in the passage of five ships carrying 120 Irish families from the Bann Valley (Coleraine-Ballymoney-Aghadowey-Macosquin).

He would practice medicine and become active in pre-revolutionary agitation before being elected to become a member of the Continental Congress in 1776. He was a Colonel of New Hampshire Militia, 1775-1783.

Thornton was sometimes used in Ireland as a synonym for Drennan, Meenagh, Tarrant, or Skehan, while other Thorntons were planted in Limerick in the 16th century.

George Read was born in Maryland in 1733. He was the son of John Read and Mary Howell Read. John Read was a wealthy resident of Dublin who emigrated to Maryland. When George Read was an infant the family moved to Delaware.

As he grew up, Read joined Thomas McKean at an Academy in Pennsylvania and then studied law. In 1763 John Penn, the Proprietary Governor, appointed Read Crown Attorney General for the three Delaware counties and he served in that position until leaving for the Continental Congress in 1774.

John Dunlap

Dunlap was born in Strabane, County Tyrone. In 1757, when he was ten years old, he went to work as an apprentice to his uncle, William Dunlap, a printer and bookseller in Philadelphia.

During the American Revolutionary War, Dunlap became an officer in the First Troop Philadelphia City Cavalry and saw action with George Washington at the battles of Trenton and Princeton.

In 1776, Dunlap secured a lucrative printing contract for the Continental Congress. On July 2, the Second Continental Congress voted to declare independence, and on July 4 they agreed to the final wording of the Declaration of Independence. That evening John Hancock ordered Dunlap to print broadsides. Dunlap printed 200 copies of the Declaration of Independence. The first newspaper outside America to publish the first text was the Belfast News Letter in its edition of August 23-27, 1776.
