The Irish surname O'Killeynd originally appeared in Gaelic as O Cillin.

Early Origins of the O'Killeynd family

The surname O'Killeynd 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, 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.

Migration of the O'Killeynd family to the New World and Oceana

A great wave of Irish migration occurred during the 19th century as a direct result of English colonial rule and tight-fisted absentee landlords. Many of these Irish immigrants boarded passenger ships bound for North America. Those who migrated early enough were given land in either British North America or the United States; those who came in the late 19th century were typically employed in industrial centers as laborers. At whatever age they undertook the dangerous passage to North America, those Irish immigrants were essential to the speedy development of the two infant nations to which they arrived, whether they broke and settled land, helped build canals, bridges, and railroads, or produced products for consumer consumption. An examination of immigration and passenger lists has uncovered a large number of immigrants bearing the name O'Killeynd or one of its variants: Jenkins Killen, who settled in Virginia in 1805; Alexander, Denis, James, John, Patrick, and Robert Killen, who all arrived in Philadelphia between 1840 and 1860.
