This surname of SIDOTI is the Americanized form of the name SZYDLOWSKI, which is a Polish name of two fold origin. It was a habitation name referring to a place where a worker in leather lived, especially a shoemaker. This was an important occupation in the life of medieval Europe, and in the cities the craftsmen were restricted by guild laws. Shoemakers who made shoes, were often forbidden to mend them. This deliberate policy of protection for their members allowed only those members to fulfill their craft. The name may also have applied to someone who shod horses, the practice of nailing iron plates or rim shoes to the hoofs of horses was in regular use during the Middle Ages. The name was also a medieval given name of uncertain origin, from ISIS, an Egyptian goddess. The name has never been common among non-Jews in western Europe; in eastern Europe it has been more popular, as it was borne by three saints of the 3rd to 5th centuries, and much venerated in the Orthodox Church. The name is also spelt SZYDLOWIECKI, SZYDLOWSKY, ISIDORO, DORRIES, SIDORSKI, IZYDORCZYK, SIDOROV, SIDORIN and SIDLO to name but a few. The earliest Polish surnames were patronymic. The personal names from which they were derived were mainly Slavonic, but as the Middle Ages progressed, traditional Slavic given names, began to give way to saint's names, mainly of Latin origin. Surnames derived from Slavonic personal names are of early origin, and tend to be borne by aristocratic families. Many Polish people acquired their surnames by reason of former residence in a town or village. There are nearly 600 families bearing the arms of a horseshoe enclosing a cross. Some names were changed by immigrants whilst on the boat heading for America and Australia. These transformations were usually to names thought by the immigrants to be more respected in their native land than the one he bore. Many Poles added 'ski' to their names to attain a higher social status since such names were accorded more respect from people of Polish extraction. Thus a larger proportion of Polish names carried this termination in America and Australia than in Poland.
