Meaning and origin of Delissio
The surname DELISSIO has its origins in Italy, specifically in the northern regions of Lombardy and Piedmont. It is believed to have emerged during the late Middle Ages, around the 13th or 14th century. The name is derived from the Italian word "liscio," which means smooth or polished, suggesting a possible connection to an occupation or trade involving smoothing or polishing materials.
One of the earliest recorded instances of the name DELISSIO can be found in a document from the city of Milan, dated 1427, where a certain Giacomo DELISSIO is mentioned as a merchant. Another early record comes from the town of Asti in Piedmont, where a family by the name of DELISSIO is documented in the 16th century.
In the 17th century, a notable figure bearing the name DELISSIO was Giovanni Battista DELISSIO (1590-1655), a renowned physician and professor of medicine at the University of Turin. He authored several treatises on medical topics and was highly regarded in his field during that time.
Another prominent individual with this surname was Francesco DELISSIO (1725-1798), a highly skilled architect and engineer from Genoa. He is credited with designing several notable buildings and structures in the city, including the Palazzo Doria Tursi, which now serves as the seat of the municipal government.
During the 18th century, the DELISSIO family had a presence in the city of Venice, where a branch of the family engaged in the silk trade. One of the most successful merchants from this lineage was Marco DELISSIO (1742-1817), whose business dealings extended throughout Europe and the Middle East.
In the 19th century, a notable figure bearing the surname DELISSIO was Giulio DELISSIO (1822-1893), a renowned painter from Turin.
