Dwier History, Family Crest & Coats of Arms
- Origins Available:
Hundreds of years ago, the Gaelic name used by the Dwier family in Ireland was O Duibhir and Mac Duibhir. These are both derived from the words dubh, which means black, and odhar or uidhir, which means uncolored. Another source has a slightly different explanation: "Descendant of the dark, tawny man; grandson of Dubhodhar (black Odhar)."  And yet another notes: "Said to be the Gaelic do-ire, a woody uncultivated place." 
Early Origins of the Dwier family
The surname Dwier was first found in County Tipperary where they were the traditional Lords of Kilnamanagh. They claim descent from Cairbre Cluitheachar, the youngest son of Cucorb, King of Leinster through the O'Connors (Faley.)  Although the O'Dwyers originally held a family seat in the barony of Kilnamanagh, they later branched to Clonyhorpa and Drumdromy in the same county. The eponymous ancestor of the O'Dwyers was Duibhir (sometimes spelled Duibhidir and Dubhiir),  the 11th century chief of the sept.

Dwier migration to the United States +
Thousands of Irish families left for North American shores in the 19th century. These people were searching for a life unencumbered with poverty, hunger, and racial discrimination. Many arrived to eventually find such conditions, but many others simply did not arrive: victims of the diseased, overcrowded ships in which they traveled to the New World. Those who lived to see North American shores were instrumental in the development of the growing nations of Canada and the United States. A thorough examination of passenger and immigration lists has disclosed evidence of many early immigrants of the name Dwier:

The Dwier 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: Vertus sola nobilitas
Motto Translation: Virtue alone enobles
