O'Connillys History, Family Crest & Coats of Arms



While many Irish names are familiar, their past incarnations are often shrouded in mystery, reflecting the ancient Gaelic heritage of their bearers. The original Gaelic form of the name O'Connillys is O Conghalaigh, O Conghaile, or O Coingheallaigh.

Early Origins of the O'Connillys family


The surname O'Connillys was first found in Connacht and Munster, as well as County Monaghan in Leinster. There were three Gaelic septs whose name was Anglicized as Connolly: the O Conghalaigh sept (also known as O Conghaile) who lived in Connacht and the adjacent County Monaghan; the O Coingheallaigh sept, which also used the alias Mac Coingheallaigh, were subordinate to the powerful O'Donovans and dwelled in West Cork in Munster; and another sept, related to the O'Maddens, resided in Connacht and were of the Ui Maine.

O'Connillys Spelling Variations


Irish names recorded during the Middle Ages are characterized by many spelling variations. This preponderance of variations for common names can be explained by the fact that the scribes and church officials that kept records during that period individually decided how to capture one's name. These recorders primarily based their decisions on how the name was pronounced or what it meant. Research into the name O'Connillys revealed many variations, including Connolly, Conolly, Connally, O'Connolly, Connolley, Conally, Connelly, Conoley, Connaleigh, Connelay, Conley, Conlay, Conlaye and many more.

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


Irish immigrants began to leave the English-controlled Ireland in sizable numbers during the late 18th century. Many of these Irish immigrated to British North America or the United States in the hopes of gaining their own tract of farmland. This pattern of migration grew steadily until the 1840s when the Great Potato Famine caused a great exodus of immigrants to North America. These immigrants differed from their predecessors in that they were desperately fleeing the disease and starvation that plagued their homeland, and many were entirely destitute when they arrived in North America. Although these penniless immigrants were not warmly welcomed when they arrived, they were critical to the rapid development of the United States and what would become known as Canada. Many went to populate the western frontiers and others provided the cheap labor the new manufacturing sector and the building of bridges, roads, railways, and canals required. A thorough examination of immigration and passenger lists has revealed some of the earliest people to arrive in North America with name O'Connillys or one of its variants: Michael and Thomas Connally who settled in Philadelphia, Pennsylvania in 1834 and 1856 respectively; M. Connolley settled in New York in 1820; John Connolly settled in Virginia in 1773.
