Show ContentsProsser History, Family Crest & Coats of Arms

The Welsh name Prosser is a patronymic surname created from the Welsh personal name Rosser, which also took the form Rhosier. The surname Prosser was originally ap-Rosser or ap-Rhosier: the distinctive Welsh patronymic prefix "ab" or "ap," means "son of," but the prefix has been assimilated into the surname over the course of time. There has also been suggestion that the name is a Welsh transformation of the Gaelic name "Mac Ruaidhri."

Early Origins of the Prosser family

The surname Prosser was first found in Herefordshire, where they held a family seat from early times and their first records appeared on the early census rolls taken by the early Kings of Britain to determine the rate of taxation of their subjects. The form Rosser was found in Chancery, where a Morres Rosser was recorded in Wales in 1100, in the "Calendar of Proceedings in Chancery" published during the reign of Elizabeth I in the 16th century.

Prosser Spelling Variations

The Welsh have an extremely large amount of spelling variations of their native surnames to their credit. It was up to the priest or the scribe taking the official records to determine how the spoken name was to be made literal. As time progressed, the old Brythonic names of Wales were recorded in English, which was especially problematic since the English language had extreme difficulty recording the highly inflected sounds of Cymraeg. Spelling variations were, however, also carried out according to an individual's design: a branch loyalty within the family, a religious adherence, or even patriotic affiliations could be indicated by spelling variations of one's name. The spelling variations of the name Prosser have included Prosser, Prousser, Proser, Prouser, Prossar, Rosser, Roser, Rossear and many more.

West Indies Prosser migration to West Indies +

The British first settled the British West Indies around 1604. They made many attempts but failed in some to establish settlements on the Islands including Saint Lucia and Grenada. By 1627 they had managed to establish settlements on St. Kitts (St. Christopher) and Barbados, but by 1641 the Spanish had moved in and destroyed some of these including those at Providence Island. The British continued to expand the settlements including setting the First Federation in the British West Indies by 1674; some of the islands include Barbados, Bermuda, Cayman Island, Turks and Caicos, Jamaica and Belize then known as British Honduras. By the 1960's many of the islands became independent after the West Indies Federation which existed from 1958 to 1962 failed due to internal political conflicts. After this a number of Eastern Caribbean islands formed a free association. 12
