McDermed History, Family Crest & Coats of Arms
Today's Irish surnames are underpinned by a multitude of rich histories. The name McDermed comes from the Irish Gaelic Mac Diarmada, which means "son of Diarmuid," or, son of Dermot and belongs to the venerable Irish tradition of patronymic naming. However another source claims the name came from the Irish diarmaid, which meant "the god of arms." 
Early Origins of the McDermed family
The surname McDermed was first found in County Roscommon (Irish: Ros Comáin) located in central Ireland in the province of Connacht, where the family is believed to have been descended from the Heremon dynasty of Irish Kings and were known as the Princes of Moylurg, or the Kings of Connacht, known as the Clann Mulroona. Specifically they were descended from Teige, a King of Connacht and his son, Murtogh, Prince of Moylurg. Their ancient territories were in the counties of Roscommon and Galway. They were divided into three septs. One of the septs embraced English rule early and relatively painlessly, the other two suffered at the hands of Strongbow's invasion in the 12th century. Of the other two septs, the more prominent is based in Coolavin, in Sligo. This sept was originally found at Moylurg and controlled a large part of Roscommon.
"The MacDermotts were ancient Princes of Moylurg, having their territories in the Barony of Boyle, County Koscommon, and parts of the Parishes of Islandeady, Turlough and Breaffy, in Counties Sligo and Mayo. Their chief fortress "was on an island in Lough Key, near Boyle," and they were hereditary Marshals of Connaught. At the present time Connaught is the province in which the MacDermotts are principally found, and half of the persons of the name in that province belong to County Roscommon. " 
The head of this branch was one of the few leaders who is still credited as an authentic chieftain by the Genealogical Office of Ireland, conferring the rightful title The MacDermot. Moreover, the chief is also unofficially styled Prince of Coolavin. The third sept held a family seat at Kilronan in the north of Roscommon, and was referred to as MacDermot Roe, from the word ruadh, which means "red."

| McDermed migration to the United States
In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the McDermed family came to North America quite early:

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: Honor probataque virtus
Motto Translation: Honour and approved valour.
