Origin
Meaning and origin of Rocamontes
The surname Rocamontes has its origins in Spain, tracing back to the 12th century. It is a toponymic name derived from the Spanish words 'roca,' meaning rock, and 'montes,' meaning mountains, likely referring to a person who lived in or near a rocky, mountainous area.
The earliest recorded instances of the Rocamontes surname can be found in medieval Spanish documents from the regions of Aragon and Catalonia. It is believed that the name may have originated from a specific place name, such as a village or hamlet, though the exact location is unknown.
In the 14th century, a nobleman named Juan de Rocamontes was mentioned in the chronicles of the Kingdom of Aragon. He was a prominent figure in the court of King Pedro IV and served as a military commander during the War of the Two Pedros against Castile.
During the 16th century, the Rocamontes family gained prominence in the region of Catalonia. Guillem de Rocamontes, born in 1520, was a renowned poet and scholar who contributed to the flourishing of Catalan literature during the Renaissance period.
Another notable bearer of the Rocamontes name was Francesc de Rocamontes, a Catalan explorer and navigator who accompanied the Spanish conquistador Hernán Cortés on his expedition to Mexico in 1519. Rocamontes played a crucial role in the conquest of the Aztec Empire and was later granted land and titles by the Spanish Crown.
In the 18th century, Diego de Rocamontes, born in 1695, was a celebrated painter and artist from Seville, Spain. His works, which were heavily influenced by the Baroque style, adorned many churches and palaces throughout Andalusia.
Over the centuries, variations of the Rocamontes surname emerged, such as Rocamonte, Rocamora, and Roquemonte, reflecting regional linguistic differences and spelling preferences. However, the core meaning and origin of the name remained rooted in the concept of a rocky, mountainous landscape.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Rocamontes surname at the time of the 2020 Census, not any inherent property of the name itself.
