When the ancestors of the Deyman family arrived in England following the Norman Conquest of 1066, they brought their name with them. It is a name for a "the dayman," a dairyman or alternatively from the occupation of a "day's man," which was a servant of the keeper of a dairy. 1

Early Origins of the Deyman family

The surname Deyman was first found in Devon where they quickly rose to be Barons Dinham shortly after the Conquest as they claimed descendancy from the Viscounts Dinant of Bretagne. 2 Some of the family were found at Steeple Aston in Oxfordshire in ancient times; unfortunately one can presume there is now little evidence of their history. "In a chapel on the north side of the chancel are recumbent effigies of Sir Francis Page and his lady, to whom the manor of Middle Aston formerly belonged: Sir Francis destroyed some monuments of the Dinham family to make room for his own, which was erected in his life-time." 3

We did find this interesting passage about the family. "Whether these Cardinans were the ancestors of the Dynhams, or Dinhams, by whom these possessions were afterwards inherited, has been a subject of dispute; some contending that they belong to the same family, and others arguing that the latter is a distinct race. By those who contend for the distinction between these families, it is said, that Isolda, the descendant, perhaps the grand-daughter, of Robert de Cardinan, being the heiress to his estates, brought this property by marriage to Thomas de Tracy, who in the year 1257 was one of the greatest landholders in Cornwall. This lady, who was left a widow, conveyed this manor as Isolda de Cardinan, who had been the wife of Thomas Tracy, to Oliver de Dinant, or Dinan, in the year 1259; which family of Dinan is said to have taken their name from Dinan in Brittany, where they had founded a monastery, and erected a castle, at a very distant period. During these descents, the name was indifferently written Dynam or Dinham, but in process of time the latter finally prevailed. In the reign of Henry VI. John Dinham, Esq. of Cardinham, who was sheriff of Devon, and resided on his barton of Nutwell." 4

"Part of the manor of Lanherne, and Kankewas, [in the manor of St. Evall, Cornwall], with all the manorial rights connected with it, was purchased by Mr. John Dayman. " 4

Deyman Spelling Variations

Endless spelling variations are a prevailing characteristic of Norman surnames. Old and Middle English lacked any definite spelling rules, and the introduction of Norman French added an unfamiliar ingredient to the English linguistic stew. French and Latin, the languages of the court, also influenced spellings. Finally, Medieval scribes generally spelled words according to how they sounded, so one person was often referred to by different spellings in different documents. The name has been spelled De Dinant, Dinan, Dinam, Dinham, Diamond, Dymond, Dyment, Diment, Dymott, Dimont and many more.

United States Deyman migration to the United States +

To escape the political and religious persecution within England at the time, many English families left for the various British colonies abroad. The voyage was extremely difficult, though, and the cramped, dank ships caused many to arrive in the New World diseased and starving. But for those who made it, the trip was most often worth it. Many of the families who arrived went on to make valuable contributions to the emerging nations of Canada and the United States. An inquiry into the early roots of North American families reveals a number of immigrants bearing the name Deyman or a variant listed above:

The Deyman 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: Toujours prest
Motto Translation: Always ready
