One of the earliest recorded instances of the name LONGI can be found in the historical documents of the city of Florence, Italy, dating back to the 13th century. In these records, a certain Giovanni Longi is mentioned as a prominent merchant and citizen of the city.

Notably, a fresco painting in the Palazzo Vecchio in Florence, completed in the late 15th century, depicts a figure identified as Matteo Longi, a renowned scholar and diplomat of the time.

As the Italian diaspora spread throughout Europe and beyond, the LONGI surname traveled with those who emigrated. In the 16th century, records show a family bearing the name LONGI settling in the Spanish city of Seville, where they established themselves as successful traders and landowners.

In the 18th century, the LONGI surname gained prominence in the field of music, with the birth of the Italian composer and violinist Francesco Longi in 1780. His compositions, which included operas, symphonies, and chamber works, were widely performed across Europe during his lifetime.

Another remarkable individual bearing the LONGI name was the Italian explorer and naturalist, Alessandro Longi, born in 1820.
