Where did the Irish Costello family come from? What is the Irish Costello family crest and coat of arms? When did the Costello family first arrive in the United States? Where did the various branches of the family go? What is the Costello family history?The Costello surname came to Ireland with the Anglo- Norman invasion of the 12th century. They were originally from the Norman family Nangles, or de Angulos, and descended in Ireland from Gilbert de Nangle. Costello and associated variations come from the personal name of a son of Gilbert, Oisdealbhach, whose name consists of the elements "os," which means "deer or fawn", and "dealbhadh," which means "in the form of" or "resembling." The Gaelic form of the surname Costello, which predated the Anglicized version of the name, is Mac Oisdealbhaigh. This is the earliest recorded example of a Norman family assuming a Mac surname. The prefix O has sometimes been erroneously assumed.
Names were simply spelled as they sounded by medieval scribes and church officials. Therefore, during the lifetime of a single person, his name was often spelt in many different ways, explaining the many spelling variations encountered while researching the name Costello. Some of these variations included: Costello, MacCostello, Costillo, Costallo, Kostello, McCostello, Caustello, Costellow and many more.
First found in County Mayo (Irish: Maigh Eo) located on the West coast of the Republic of Ireland in the province of Connacht, where they were granted lands by the Earl of Pembroke in the Anglo- Norman invasion of 1172.

Irish immigration to North American began in the late 18th century as many Irish families desired to own their own land. This pattern of immigration grew slowly yet steadily until the 1840s. At that time, a failed crop and a growing population in Ireland resulted in the Great Potato Famine. Poverty, disease, and starvation ravaged the land. To ease their pain and suffering the Irish often looked upon North America as a solution: hundreds of thousands undertook the voyage. Their arrival meant the growth of industry and commerce for British North America and the United States. For the individual Irishman, it meant survival and hope, and the opportunity for work, freedom, and ownership of land. The early immigration and passenger lists revealed many bearing the name Costello:

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: Ne te quaesiveris extra
Motto Translation: Seek nothing beyond your sphere.
The Costello Family Crest was acquired from the Houseofnames.com archives. The Costello Family Crest was drawn according to heraldic standards based on published blazons. We generally include the oldest published family crest once associated with each surname.
