From the ancient and picturesque Italian region of Lombardy emerged a variety of distinguished names, including the notable surname Bosi. Although people were originally known only by a single name, it became necessary for people to adopt a second name to identify themselves as populations grew and travel became more frequent. The process of adopting fixed hereditary surnames was not complete until the modern era, but the use of hereditary family names in Italy began in the 10th and 11th centuries. Italian hereditary surnames were developed according to fairly general principles and they are characterized by a profusion of derivatives coined from given names. Although the most traditional type of family name found in the region of Lombardy is the patronymic surname, which is derived from the father's given name, local surnames are also found. Local names, which are the least frequent of the major types of surnames found in Italy, are derived from a place-name where the original bearer once resided or held land. Often Italian local surnames bore the prefix "di," which signifies emigration from one place to another, but does not necessarily denote nobility. The Bosi family lived in the city of Milan. The Bosi surname is derived from the Latin personal name "Bosius."

Early Origins of the Bosi family

The surname Bosi was first found in 1170, where Consabecco Bossi was part of the Commune of Milan.

Boso (d. 1181?), was the third English cardinal, "described by Cardella as Boso Breakspear, an Englishman by birth, the nephew of Pope Adrian IV, and a monk of the order of St. Benedict. He was a member of the monastery of St. Albans, but went to Rome to follow the fortunes of his uncle." 1

Bosi Spelling Variations

Italian surnames come in far more variations than the names of most other nationalities. Regional traditions and dialects are a decisive factor in this characteristic. For example, northern names tend to end in "o", while southern in "i". Also important, but not unique to Italy, was the fact that before dictionaries and the printing press most scribes simply spelled words according to their sounds. The predictable result was an enormous number of spelling variations. The recorded spellings of Bosi include Bosio, Bsio, Bsia, Bso, Bosia, Boso, Bsi, Bosi, Busio, Buosio, Busi, Buosi, Bosich, Bosèlli, Bosèllo, Boselli, Bosello, Bosè, Bose, Bosetti, Bosètti, Bosini, Bosìn, Bosin, Bosinèlli, Bosinelli, Bostti, Bosotti, Bosni, Bosoni, Bosne, Bosone, Bosani, Bosèro, Bosero, Bossa, Bossi and many more.
