The name can be traced back to the 13th century, with records showing the Mignanelli family residing in the town of Perugia, Umbria. In 1275, a document mentions a certain Guglielmo Mignanelli, who was a prominent citizen of the town.
In the 14th century, the Mignanelli family gained prominence in the city of Florence, Tuscany. Records from that time mention a Bernardo Mignanelli, who was a wealthy merchant and landowner, born in 1320 and died in 1392.
During the Renaissance period, the Mignanelli family produced several notable figures. One of them was Fabio Mignanelli, a renowned architect and sculptor born in 1480 in Florence. He is credited with designing several churches and palaces in the city, including the Palazzo Mignanelli, which still bears his family's name.
Another famous Mignanelli was Giovanni Battista Mignanelli, a Cardinal of the Catholic Church, born in 1536 in Perugia. He played a significant role in the Council of Trent and was known for his diplomatic skills.
In the 18th century, the Mignanelli family had a presence in the Kingdom of Naples. A notable figure from that time was Antonio Mignanelli, a lawyer and judge who served in the court of King Ferdinand IV of Naples. He was born in 1725 and died in 1803.
Throughout history, the surname Mignanelli has also been associated with various place names, such as Mignanello, a small town in the province of Frosinone, and Mignanella, a frazione (subdivision) of the municipality of Città di Castello in Umbria. These place names are likely derived from the same root as the surname, indicating the family's connection to these areas.
