Show ContentsBlackmer History, Family Crest & Coats of Arms

The present generation of the Blackmer family is only the most recent to bear a name that dates back to the ancient Anglo-Saxon culture of Britain. Their name comes from having lived in the area of Blackmore. Early members lived near one of two places named Blakmore, a parish in the diocese of Winchester, and a parish in the diocese of St. Albans. The place-name is derived from the Old English words blaec, meaning black, and mor, meaning marsh, and would have been used to name a settlement near a dark marsh. Another source notes the name could have meant ‘dweller by the dark mere’ from the Old English 'blæc' + 'mere', from the Old English 'blæc,' and the Middle English 'Mor' ‘a Moor’.1

Early Origins of the Blackmer family

The surname Blackmer was first found in the Domesday Book of 1086 where Blachemer was recorded in Shropshire (Salop.) 2 Years later, William de Blakemere was recorded in the Subsidy Rolls for Worcestershire in 1275 and later, Kateryna de Blakemere was registered in Herefordshire in 1296. 1

Baldwin de Blakomor was listed in the Pipe Rolls for Devon in 1200, as was Nicholas de Blakemore in the Assize Rolls for Staffordshire in 1307. 1

In Somerset, Margery de Blakemor was recorded there 1 Edward III (in the first year of King Edward III's reign.) 4

The Hundredorum Rolls of 1273 included: Richard de Blakemore, Oxfordshire; and (Prior) de Blakemore, Essex. 5

"The Blackmores are now numerous in Honiton and its neighbourhood, There is (or was) an epitaph in the Middle Temple church to Mark Blackmore, son of Mark Blackmore, of Harpford, in the county of Devon, gent. (Dugdale's "Orig. Jur. "), which cannot bear a later date than the early part of the 17th century. A family of the name lived in Exmouth last century: in 1746 Mr. Blackmore "leaded ye tower;" and in 1771 and 1811 William and John Blackmore were clerks of Exmouth Chapel (Webb) Blackmore and Blackmoor are places in Essex, Wilts, and other counties. Blakemore is now a Shropshire surname. Blakema and De Blakemor were surnames in Bucks, Oxon, and Essex six centuries ago." 6

United States Blackmer migration to the United States +

Thousands of English families boarded ships sailing to the New World in the hope of escaping the unrest found in England at this time. Although the search for opportunity and freedom from persecution abroad took the lives of many because of the cramped conditions and unsanitary nature of the vessels, the opportunity perceived in the growing colonies of North America beckoned. Many of the settlers who survived the journey went on to make important contributions to the transplanted cultures of their adopted countries. The Blackmer were among these contributors, for they have been located in early North American records:

The Blackmer 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: Pro Deo
Motto Translation: For God.
