The surname Caillion is derived from the personal name Hugelin, which is a diminutive of Hugh. The Gaelic form of the name is Mac Uighilin.

Early Origins of the Caillion family

The surname Caillion was first found in County Antrim (Irish: Aontroim) located in the province of Ulster in present day Northern Ireland, where they were granted lands by Strongbow after the Anglo/Norman invasion of Ireland in 1172.

Specifically, "The MacQuillans were lords of the territory of the Routes, in co. Antrim, holding their chief residence in the fine old sea-girt castle of Dunluce." MacLysaght agrees "The MacQillans are of Norman-Welsh descent: they settled soon after the invasion in the territory called the Route (co. Antrim.)" 1

One of the first records of the family was Malcolm MacQuillan who died in 1307. Little is known of his heritage, but what we do know is that he was granted safe conduct by the English so he could assail Scottish forces, on Scotland's western seaboard, with his galley fleet. He was part of a fleet of eighteen galleys with 1,000 men who landed near Stranraer, now a town in southwest Scotland in Inch, Dumfries and Galloway. But, this force was quickly overwhelmed by local forces led by Dungal MacDouall. MacQuillan was captured and executed. His head and the heads from two Irish chiefs were sent back to King Edward I.

Migration of the Caillion family

A great number of Irish families left their homeland in the late 18th century and throughout the 19th century, migrating to such far away lands as Australia and North America. The early settlers left after much planning and deliberation. They were generally well off but they desired a tract of land that they could farm solely for themselves. The great mass of immigrants to arrive on North American shores in the 1840s differed greatly from their predecessors because many of them were utterly destitute, selling all they had to gain a passage on a ship or having their way paid by a philanthropic society. These Irish people were trying to escape the aftermath of the Great Potato Famine: poverty, starvation, disease, and, for many, ultimately death. Those that arrived on North American shores were not warmly welcomed by the established population, but they were vital to the rapid development of the industry, agriculture, and infrastructure of the infant nations of the United States and what would become Canada. Early passenger and immigration lists reveal many Irish settlers bearing the name Caillion: Andrew, Charles, James, John, Patrick, William McQuillan arrived in Philadelphia between 1840 and 1860; Edward, George, Patrick, Phillip, Roger and Thomas McQuillen all arrived in Philadelphia between 1840 and 1860.
