Early Origins of the Synnott family

The surname Synnott 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.

Migration of the Synnott family

Ireland experienced a dramatic decrease in its population during the 19th century. This was in a great measure, a response to England's imperialistic policies. Hunger and disease took the lives of many Irish people and many more chose to leave their homeland to escape the horrific conditions. North America with its promise of work, freedom, and land was an extremely popular destination for Irish families. For those families that survived the journey, all three of these things were often attained through much hard work and perseverance. Research into early immigration and passenger lists revealed many immigrants bearing the name Synnott: Edward Sinnott, who was on record in Torbay, Newfoundland in 1774; Dennis Sinnott, who arrived in New York in 1789; Moses Sinnot, who came to Vermont in 1854.

The Synnott 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
