Early Origins of the Killeen family

The surname Killeen was first found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they held territories was at Ballykilleen since early times. This lofty family were the ancient Chiefs of Fingal, Earls of Fingal and Lords Killeen.

Saint Kilian, (also spelled Killian) from the Irish: Cillian, (c. 640-689) was an Irish missionary bishop and the apostle of Franconia. He was born in Mullagh, County Cavan, and is the patron saint of the parish of Tuosist, in County Kerry. Saint Kilian's feast day is July 8th and St. Kilian's Abbey, at Würzburg is named after him.

Today there are two Killeen Castles in Ireland: one located at Dunsany, in County Meath, that dates back to about 1180, but today's structure is a restoration of the 19th century after a fire in 1981. It will include a luxury golf course designed by Jack Nicklaus. The second Killeen Castle is a 17th century castle at Killeen, in Castlegar, County Galway.

There are some scanty records of the family in Scotland, but they are rather late: "John Killan in Cleckaime, parish of Lesmahago, 1677, and Robert Killand in Deidwatters, parish of Lesmahago, 1678. This name in Irish is O'Cilleain, descendant of Cillean, a diminutive of Ceallach, an ancient and once very common name." 2

Suffering from poverty and racial discrimination, thousands of Irish families left the island in the 19th century for North America aboard cramped passenger ships.

Although the immigrants from this period were often maligned when they arrived in the United States, they provided the cheap labor that was necessary for the development of that country as an industrial power.
