The history of the last name Isoldi

The surname Isoldi originates from Italy, specifically the Tuscany region, where it first emerged in the 12th century. It is derived from the Italian personal name Isaldo, which itself comes from the Germanic name Iswald, meaning "ruler of the estate." The earliest recorded spelling of the name was Isoaldi.

One of the earliest known bearers of the name was Guglielmo Isoaldi, a nobleman from Florence who lived in the late 12th century. His name appears in several legal documents and records from that time period. Another early mention of the name is found in the Codice Diplomatico Longobardo, a collection of historical documents from the Lombard period, where a certain Uberto Isoaldi is referenced in the year 1207.

The Isoldi surname can also be traced back to the village of Isoldi near Siena in Tuscany. It is believed that some members of the family may have taken their name from this place. In the 14th century, a branch of the Isoldi family settled in the town of Montepulciano, where they became prominent landowners and merchants.

One of the most famous bearers of the Isoldi name was Girolamo Isoldi (1503-1556), a renowned Italian physician and philosopher from Siena. He wrote several influential works on medicine and natural philosophy, including "De Remediis Febrium" and "De Morbis Puerorum." Another notable Isoldi was Cesare Isoldi (1537-1609), an Italian composer and organist who served at the court of the Gonzaga family in Mantua.

In the 16th century, the Isoldi family also produced several notable artists and architects.
