The surname DELMORO has its origins in Spain, with the earliest records dating back to the 16th century. It is believed to have originated from the Spanish phrase "del moro," which translates to "of the Moor" or "of the Arab." This suggests that the name may have been given to individuals or families with connections to the Moorish population that once lived in parts of the Iberian Peninsula.
During the Reconquista period in Spain, as Christian kingdoms gradually regained control over territories previously ruled by the Moors, it was common for individuals or families with Moorish ancestry or ties to be identified with surnames reflecting their heritage. The name DELMORO could have been used to distinguish those with Moorish roots or associations.
One of the earliest documented references to the name DELMORO can be found in the parish records of the city of Seville, where a certain Juan DELMORO was recorded as a resident in the year 1587. This suggests that the name was already in use by that time in the southern region of Andalusia, which had a significant Moorish influence and history.
In the 17th century, records show that a family bearing the surname DELMORO settled in the region of Catalonia, in northeastern Spain. A notable figure from this lineage was Jaume DELMORO, a merchant who lived in Barcelona during the late 1600s and was involved in the textile trade with other Mediterranean countries.
As the name spread across Spain, variations in spelling and pronunciation emerged, such as DELMORA, DELMORÓ, and DELMORÍ. These variations likely reflected regional linguistic differences and the influence of local dialects.
Another individual of note was María DELMORO, a writer and poet born in Madrid in the early 19th century. Her works, which explored themes of love and nature, were published in various literary journals of the time.
In the 20th century, the DELMORO surname gained recognition through the achievements of Manuel DELMORO, a renowned Spanish architect who designed several notable buildings in Barcelona and Valencia between the 1920s and 1960s.
While the name DELMORO is not among the most common surnames in Spain today, it has a rich history that can be traced back to the country's Moorish heritage and the cultural exchanges that occurred during the Reconquista period.
