Champin History, Family Crest & Coats of Arms
The name Champin was brought to England in the wave of migration that followed the Norman Conquest of 1066. It is a name for a professional champion. In the Middle Ages a common manner of settling disputes was through trial by combat. Thus, proficient fighters would sell their services to represent parties involved in such cases by fighting on their behalf. The word derives from the Anglo Norman French word, campion, of the same meaning. 
We found this interesting passage that explores the "champion" aspect in more detail: "In the ordeal by battle, in criminal cases, the accuser and the accused took the field themselves, but in disputes about the ownership of land, the actual parties to the suit were represented by 'champions', in theory their free tenants, but in practice, hired men, professional champions, and very well paid. In 1294 the Dean and Chapter of Southwell incurred a prospective liability of about £750 in modern money in hiring a champion to fight a duel to settle a law-suit about the advowson of a church. A pugil or champion was a regular member of the household of more than one medieval bishop, Thomas Cantilupe, Bishop of Hereford (1275-1282), paying his champion, Thomas de Bruges, a salary of half a mark a year."

The voyages were expensive, crowded, and difficult, though, and many arrived in North America sick, starved, and destitute. Those who did make it, however, were greeted with greater opportunities and freedoms that they could have experienced at home. Many of those families went on to make important contributions to the young nations in which they settled. Early immigration records have shown some of the first Champins to arrive on North American shores:
