English : from an agent derivative of Middle English wasch(en) ‘to wash’ (Old English wæscan), hence an occupational name for a laundryman, or for someone who washed raw wool before spinning. Various other occupations, too, involved washing processes and the name may relate to any of these. For example, it may have denoted a man who washed sheep; some tenants on the manor of Burpham, near Worthing, in Sussex (where the surname is found from an early date), had as part of their feudal service to wash the flocks of their master.Americanized spelling of the German cognate Wascher.

English : occupational name for a medieval court official, from Middle English bedele (Old English bydel, reinforced by Old French bedel). The word is of Germanic origin, and akin to Old English bēodan ‘to command’ and Old High German bodo ‘messenger’. In the Middle Ages a beadle in England and France was a junior official of a court of justice, responsible for acting as an usher in a court, carrying the mace in processions in front of a justice, delivering official notices, making proclamations (as a sort of town crier), and so on. By Shakespeare’s day a beadle was a sort of village constable, appointed by the parish to keep order.

English and Scottish : occupational name for an archer, Middle English bow(e)man, bouman (from Old English boga ‘bow’ + mann ‘man’). This word was distinguished from Bowyer, which denoted a maker or seller of the articles. It is possible that in some cases the surname referred originally to someone who untangled wool with a bow. This process, which originated in Italy, became quite common in England in the 13th century. The vibrating string of a bow was worked into a pile of tangled wool, where its rapid vibrations separated the fibers, while still leaving them sufficiently entwined to produce a fine, soft yarn when spun.Americanized form of German Baumann (see Bauer) or the Dutch cognate Bouman.

In a few cases the surname may have been given originally to someone who lived by a crossroads, but this sense of the word seems to have been a comparatively late development. In other cases, the surname (and its European cognates) may have denoted someone who carried the cross in processions of the Christian Church, but in English at least the usual word for this sense was Crozier.Irish : reduced form of McCrossen.In North America this name has absorbed examples of cognate names from other languages, such as French Lacroix.
