O'Lavertie History, Family Crest & Coats of Arms
The Irish surnames in use today are underpinned by a multitude of rich histories. The name O'Lavertie originally appeared in Gaelic as "O Flaithbheartaigh," which means "bright ruler."
Early Origins of the O'Lavertie family
The surname O'Lavertie was first found in Connemara (Irish : Conamara), which derives from Conmhaicne Mara (meaning: descendants of Con Mhac, of the sea)), County Galway in Connacht where the name claims descent from Flaithbertaigh Ua Flaithbertaigh, King of Connacht, who died 1098. Flaithbertaigh was the first bearer of the surname O'Flaherty, and was Lord of Maigh Seola in what is now County Galway. 
"The O'Flahertys were originally located in the Barony of Clare, County Galway, but in the thirteenth century, having been expelled from this territory, they settled in the Barony of Moycullen, and were styled Lords of lar Conacht or West Connaught. A large number of the Flahertys are now to be found in the Baronies of Moycullen, Ross, and Ballinahinch, in County Galway." 
Another source gives this background about the family: "This family, whose tribe name was Muintir Murchadha, traced their descent from Flaibheartach, twenty-second in descent from Eochaidh Muighmeadhon, king of Ireland, who died in 366. They were at first settled in Magh Seola, to the east of Lough Corrib, but in the thirteenth century were driven from their original home by the O'Connors, and conquered a new territory in West Connaught from Lough Corrib to the sea. There were several septs of the clan."

Migration of the O'Lavertie family
Ireland saw an enormous decrease in its population in the 19th century due to immigration and death. This pattern of immigration began slowly in the late 18th century and gradually grew throughout the early portion of the 19th century. However, a dramatic increase in the country's immigration numbers occurred when the Great Potato Famine struck in the 1840s. The early immigrants to North America were primarily destined to be farmers tending to their own plot of land, those that came later initially settled within pre-established urban centers. These urban immigrants provided the cheap labor that the fast developing United States and soon to be Canada required. Regardless of their new lifestyle in North America, the Irish immigrants to the United States and Canada made invaluable contributions to their newly adopted societies. An investigation of immigrant and passenger lists revealed many O'Laverties: James Flaherty who landed in Virginia in 1651; followed James Flaharty in 1651; Timothy Flaharty settled in Boston Massachusetts in 1767; Ann Flaherty settled in New York in 1850.
