Patronyms are usually given but even when surnames are used, a married woman may sometimes be known by her husband's surname. Parish registers do not stop at baptisms, marriages and burials. They also include periodical State of Souls registers. These were compiled by the parish priest who followed a more or less standardised route through the town, listing each person and the house in which they lived with varying additional information. Usually parents are given, relationships within the household and whether the person was confirmed and a communicant.
Most states of souls give ages, but few occupations.
Some also list origins consistently. Ascoli has several such a listings of eighteenth and nineteenth century date. Quenza has them from the seventeenth and eighteenth centuries plus sporadic nominative census lists from 1770 until 1962. Economic data is rather less accessible. The magisterial Catasto Onciario of the mid 18th century is a survey of taxable property in Southern Italy with listings of population but no map.
