Irish surnames are linked to the long Gaelic heritage of the Island nation. The original Gaelic form of the name O'Gara is "O Gadhra," which is derived from the word "gadhar," which means "dog."

Early Origins of the O'Gara family

The surname O'Gara was first found in County Sligo (Irish: Sligeach), in the province of Connacht in Northwestern Ireland, where they were Chiefs of Coolavin aad Sliabh Lugha. 1

The surname also spelled Gara, O'Gara, and Gerry is descended from Tiachleach, Lord of South Leyney who was killed in 964 A.D. The Geary family was closely associated with the O'Haras from an early time and the chiefs of the two septs alternated as rulers of Luighne. 2

"The O'Garas were lords of the territory of Luighne, now forming and giving name to the barony of Leyney or Lieny, in the county of Sligo, whence they were expelled by the MacSurtains and the Mac Costelloes, families of Anglo-Norman descent." 1

Once more into the archives we delved to find life in early times was fraught with battles and deaths. By example, some of the first entries of the family include: Tiachleach O'Gara, slain in 964; Rory O'Gara, tanist of Leyney, slain; Rory O'Gara, heir presumptive died in 1059; Donlevy O'Gara, lord of Leyney, killed by Brian O'Hara; O'Gadhra, lord of Layney, slain at battle of Ardee; and O'Gara, lord of Sliabh-Lugha, died. 1

Migration of the O'Gara family

In the 18th and 19th centuries hundreds of thousands of Irish people immigrated to North American shores. The early settlers were enticed by the promise of their own land, but they were moderately well off in Ireland when they decided to emigrate. Therefore, they were merely carrying out a long and carefully thought out decision. The 1840s saw the emergence of a very different trend: thousands of extremely desperate people crammed into passenger boats hoping to find any type of opportunity. The Irish of this decade had seen their homeland severely stricken by crop failures which resulted in widespread disease and starvation. At whatever time the Irish immigrants came to North America, they were instrumental in the rapid development of the emerging nations of the United States and what would become known as Canada. An exhaustive search of passenger and immigration lists has revealed many persons bearing the name O'Gara, or one of its variants: John Geary, who landed in Pennsylvania in 1682; Eleanor Geary, who landed in America in 1744; Mary Geary, who landed in New York State in 1822; Jeremiah, John, Michael, Patrick, who all settled in Philadelphia, Pa. between 1773 and 1858.

The O'Gara Motto +

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.

Motto: Fortiter et fideliter
Motto Translation: Boldly and faithfully.
