Lammoourn History, Family Crest & Coats of Arms
The Lammoourn history begins in Cornwall, a rugged coastal region in southwestern England. Quite distinct from Devon, the adjoining county, Cornwall had its own spoken language until the late 18th century. The Lammoourn history began here. The manner in which hereditary surnames arose is interesting. Local surnames were derived from where the original bearer lived, was born, or held land. Unlike most Celtic peoples, who favored patronymic names, the Cornish predominantly used local surnames. The Lammoourn family originally lived in Cornwall, in the village of Lamborne where one source notes the name was "anciently written in the Cornish-British Lambron, the inclosure of the round hill; lan being changed into lam, for the sake of the euphony or ease in speaking; from the Welsh Llan, an inclosure, and bryn, a hill." 
Like many names from Cornwall, we must look to Normandy for the origin of the family. It is there we found in the Magni Rotuli Scaccarii Normanniae an entry for Alvered de Lamborne, Normandy 1180-1195.  When they ventured to England is not known.
Lambourn is a parish, in the union of Hungerford, hundred of Lambourn, in Berkshire and this "place formed part of the dower of Ealswitha, queen of Alfred the Great, and continued in royal demesne under Edward the Confessor; after the Conquest it was given to the baronial family of Fitzwarren, at whose instance a market and three fairs were granted to it by Henry III. " 
The place name literally means "stream where lambs are washed," from the Old English "lamb"+ "burna."  The Berkshire parish is the oldest dating back to Saxon times when it was known as Lambburnan c. 880 and later in the Domesday Book of 1086 it was listed as Lamborne. 
Lambourne in Essex also dates back to the Domesday Book when it was known as Lamburna. 
Early Origins of the Lammoourn family
The surname Lammoourn was first found in Cornwall where the family held an estate in the parish of Perran Zabuloe dating back to the reign of Edward II.  
"In the days of Edward III. about 1330, these lands [of Lamburn, Cornwall] belonged to Sir John Lamburn of Lamburn, in Perransand, whose daughter and heir was married to one of the Arundells of Lanherne." 
Ralph de Lamburne was listed in the Feet of Fines for Essex in 1198 and later, Alice de Lamborne was found in Wiltshire in 1278. 
The Hundredorum Rolls of 1273 includes: William de Lamburne, Suffolk; Alicia de Lamburne, Oxfordshire; and Lambekin de Lamburne, London.

Lammoourn Spelling Variations
Cornish surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are due to the fact that the Old and Middle English languages lacked definite spelling rules. The official court languages, which were Latin and French, were also influential on the spelling of a surname. Since the spelling of surnames was rarely consistent in medieval times, and scribes and church officials recorded names as they sounded rather than adhering to any specific spelling rules, it was common to find the same individual referred to with different spellings of their surname in the ancient chronicles. Moreover, a large number of foreign names were brought into England, which accelerated and accentuated the alterations to the spelling of various surnames. Lastly, spelling variations often resulted from the linguistic differences between the people of Cornwall and the rest of England. The Cornish spoke a unique Brythonic Celtic language which was first recorded in written documents during the 10th century. However, they became increasingly Anglicized, and Cornish became extinct as a spoken language in 1777, although it has been revived by Cornish patriots in the modern era. The name has been spelled Lamborne, Lambourne, Lamborn, Lambourn and others.
