Sinnott History, Family Crest & Coats of Arms

Early Origins of the Sinnott family

The surname Sinnott was first found in County Wexford (Irish: Loch Garman), founded by Vikings as Waesfjord, and located in Southeastern Ireland, in the province of Leinster. "Descended from an honourable stock, of Norman extraction. They were possessed of lands in Ireland from the time of the Invasion, and in the county where they first found footing." [1] They claim descent from the Marquis of Lusignan, whose descendants came into England, at or soon after the Norman Conquest.

United States Sinnott migration to the United States +

In the mid-19th century, Ireland experienced one of the worst periods in its entire history. During this decade in order to ease the pressure of the soil, which was actually depleted by the effects of the previous years' grain crops, landowners forced tenant farmers and peasants onto tiny plots of land that barely provided the basic sustenance a family required. Conditions were worsened, though, by the population of the country, which was growing fast to roughly eight million. So when the Great Potato Famine of the mid-1840s hit, starvation and diseases decimated the population. Thousands of Irish families left the country for British North America and the United States. The new immigrants were often accommodated either in the opening western frontiers or as cheap unskilled labor in the established centers. In early passenger and immigration lists there are many immigrants bearing the name Sinnott:

The Sinnott 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: Sin not
Motto Translation: If not
