Origin
Meaning and origin of Dadura
The surname Dadura has its roots in the Galician region of northwestern Spain, tracing back to the 12th century. It is believed to be derived from the old Galician word "dadu", meaning "given" or "bestowed", suggesting it may have originated as a descriptive name referring to someone who was given or bestowed something.
One of the earliest recorded instances of the name Dadura appears in the Tombo de Sobrado, a cartulary from the Monastery of Santa Maria de Sobrado, dated around 1195. This manuscript contains references to individuals bearing the name, indicating its presence in the region during the medieval period.
The name Dadura is also found in the Tumbo de Fieiras, a 13th-century cartulary from the Monastery of Santa Maria de Fieiras, near Ourense, in Galicia. This document includes various mentions of individuals with the surname, further solidifying its historical roots in the area.
Notably, in the 14th century, a prominent figure named Pedro Dadura was a prominent landowner and nobleman in the Galician town of Ribadavia. His name appears in several historical documents from that era, cementing the name's association with the region's nobility.
Another notable bearer of the surname was Rodrigo Dadura, a 15th-century writer and poet from the town of Tui, in Galicia. His literary works, which include poetic compositions in the Galician-Portuguese language, have been preserved and studied by scholars, providing valuable insights into the cultural and linguistic heritage of the region.
In the 16th century, the name Dadura was also present in the town of Vigo, as evidenced by the records of Juan Dadura, a merchant and ship owner who played a significant role in the town's maritime trade during that period.
Over the centuries, the surname Dadura has maintained its presence in various parts of Galicia, with variations in spelling such as Dadura and Dadura appearing in historical records. While the name has not achieved widespread fame outside of its region of origin, it remains an integral part of Galicia's cultural and historical tapestry.

Does the Census include every surname?
