McIleese History, Family Crest & Coats of Arms

As a native Irish surname, McIleese is derived from the Gaelic name Mac Laoidhigh, which comes from the word "laoidh," which means "a poem;" or from Mac Giolla Iosa, which means "son of the devotee of Jesus." However, Lee is also a common indigenous name in England, many families of which have been established in Ireland since at least the 17th century. [1]

Early Origins of the McIleese family

The surname McIleese was first found in Connacht (Irish: Connachta, (land of the) descendants of Conn), where they were prominent in the west being anciently associated as hereditary physicians to the O'Flahertys.

Families with the McLees or McAlees spellings were traditionally doctors or physicians.

By the 16th century different branches had developed in Galway, in Leix, and in Munster at Cork and Limerick. The name in Gaelic was O'Laidhigh.

Migration of the McIleese family

Irish families left their homeland in astonishing numbers during the 19th century in search of a better life. Although individual reasons vary, most of these Irish families suffered from extreme poverty, lack of work opportunities, and exorbitant rents in their homeland. Many decided to travel to Australia or North America in the hopes of finding greater opportunities and land. The Irish immigrants that came to North America initially settled on the East Coast, often in major centers such as Boston or New York. But like the many other cultures to settle in North America, the Irish traveled to almost any region they felt held greater promise; as a result, many Irish with gold fever moved all the way out to the Pacific coast. Others before that time left for land along the St. Lawrence River and the Niagara Peninsula, or the Maritimes as United Empire Loyalists, for many Irish did choose to side with the English during the American War of Independence. The earliest wave of Irish migration, however, occurred during the Great Potato Famine of the 1840s. An examination of early immigration and passenger lists has revealed many people bearing the McIleese name: Hugh O'Lee, who settled in Maryland in 1658; William McLea, who arrived in New York in 1775; James McLea, who settled in Savannah Georgia in 1821; Biddy Lees, who arrived in St. John, N.B. in 1834 aboard the Brig ".



The McIleese 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: Fide et fortitudine
Motto Translation: By fidelity and fortitude.
