Where did the Italian Deblasio family come from? What is the Italian Deblasio family crest and coat of arms? When did the Deblasio family first arrive in the United States? Where did the various branches of the family go? What is the Deblasio family history?

The distinguished surname Deblasio originated in an area of Italy, known as the Papal States. Although people were originally known only by a single name, it became necessary for people to adapt 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 the Papal States 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 Deblasio family lived in the city of Benevento, which lies east of Naples. Earliest records date back to the 14th century, when the Blasio family branched from this town to Bari, Catanzaro, and Reggio di Calabria.


Surnames that originated in Italy are characterized by an enormous number of spelling variations. Some of these are derived from regional traditions and dialects. Northern names, for instance, often end in "o", while southern names tend to end in "i". Other variations come from the fact the medieval scribes tended to spell according to the sound of words, rather than any particular set of rules. The recorded variations of Deblasio include Biaggi, Biagi, Biasi, Biasii, Biasio, Biase, Blasi, Blasio, Biagini, Biagia, Blase, Blas, De Biagi, De Biaggi, De Biasi, Debiasi, De Biase, De Blasi, De Blasio, De Blase, De Blasis, De Blasiis, De Biagio, Di Biasi, Di Biasio, Di Biaso, Di Biase, Di Blasi, Di Blas, Blasich, Blasic, Blasig, Blasigh, Blasevich, Biagelli, Biagetti, Beagini, Biagioli, Biagiotti, Biagioni, Biagianti, Biasetti, Biasetton, Biasini, Biasin, Biasioli, Biasiolo, Biasol, Biasotti, Biasiotti, Biasuz, Biasioni, Biasione, Biasone, Biason, Biasiutti, Biasiutto, Biasutti, Biasutto, Blasetti, Blasini, Blasina, Blasoni and many more.
