Since the early Middle Ages a term (also Hube, Huffe, Lahn derived from fiefdom) used for a farm or homestead (farm) with sufficient arable and pasture land that a family could work and feed. Depending on their size, the owners had corresponding designations such as Vollbauer or Huber (1 Hufe/Hube), Halbbauer (1/2 Hufe/Hube), Viertelbauer (¼ Hufe/Hube) and Kleinhäusler (at ¼ Hufe/Hube), which was used as a common family name. The hooves also served as a measurement unit for the collection of the manorial taxes and services. From the 9th to the 18th century, this was also used to designate an area or field measure. The size varied considerably between 20 and 160 acres, or 5 to 40 hectares, depending on the type of soil and land. One king hoof corresponded to two hooves.
