All these surnames likely derive, directly or through various hypocoristic forms, from nicknames related to the activity of a drummer or "banditore" (town crier) that the first bearers of the surname probably performed. In the medieval era, the town crier of the commune was called "tamburellus," who, with the sound of the drum, attracted the attention of people to whom he had to communicate the announcements or notices from the country's authorities. It could also refer to the role of a drummer, in the military or as a town crier, or to events related to the use of the drum. **Tamurri** likely originated from a transcription error of one of the surnames mentioned above.
