Hernaldo is of Spanish origin, derived from the Germanic elements heri, meaning "army," and nald, which means "power" or "rule." This suggests that Hernaldo was once a Germanic name that became popular in Spain through the influence of the Visigoths who settled there around the 5th century. The name is composed of two distinct parts, creating a unique sound that sets it apart from other Spanish names. It has not gained widespread international recognition but is nonetheless considered a distinctive and somewhat unusual choice for a given name.
Hernaldo had 5 births in 1987 and another 5 births in 1994, making a total of 10 births over those two years.
