Morryarty 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 Morryarty is O Muircheartaigh, which is derived from the word "muircheartach," which means "navigator."

Early Origins of the Morryarty family

The surname Morryarty was first found in County Kerry (Irish:Ciarraí) part of the former County Desmond (14th-17th centuries), located in Southwestern Ireland, in Munster province.

"The name Moriarty is now largely represented in County Kerry, in which county the O'Moriartys were Chiefs in the Barony of Dunkerron." [1]

The fictional Professor James Moriarty in some of the Sherlock Holmes stories written by Sir Arthur Conan Doyle was based on Doyle's discussions with a Scotland Yard inspector and his knowledge of Adam Worth (1844-1902), the German-born American criminal mastermind.

Migration of the Morryarty family

Irish families began leaving their homeland for North America in the late 18th century. These families were usually modestly well off, but they were looking forward to owning and working on a sizable tract of land of their own. This pattern of emigration continued until the 1840s when the Great Potato Famine sparked a major exodus of destitute and desperate Irish people. These people were not leaving for a grant of land in North America because by this time the East Coast had reached its saturation point and free land was scarce. They were merely looking to escape the disease, starvation, and hopelessness that Ireland had fallen into. Although these unfortunate immigrants did not receive a warm welcome by the established populations in the United States and what would become Canada, they were absolutely critical to the rapid development that these two nations enjoyed. They would help populate the western lands and provide the cheap labor required for a rapid industrialization. An examination of passenger and immigration lists has revealed many early bearers of the name Morryarty or one of its variants: Daniel, Ellen, Eugene, Margaret, Michael, Thomas Moriarty, who all settled in Boston in 1849; James, John, Martin, Maurice, and Michael Moriarty all arrived in Philadelphia between 1840 and 1860..
