Del Rosario
A Spanish surname meaning “of the Rosary,” originally marking devotion to the Virgin Mary and the rosary prayer.
The #4,218 most common surname in the United States (2010 Census) — about 1 in every 36,747 Americans shares it.
Etymology
Del Rosario is a Spanish surname built from the preposition del, meaning “of the,” and Rosario, “Rosary.” Rosario ultimately comes from Latin rosarium, “rose garden,” which in Christian use became the name for the rosary prayer and, by extension, the Virgin Mary under the title Our Lady of the Rosary. The surname therefore began as a religious or devotional name, most likely adopted in reference to a shrine, feast, devotion, or baptismal naming tradition rather than as a hereditary family label at first.
History
Surnames of this type are especially common in Spanish-speaking Catholic communities and in places influenced by Spanish naming customs, including the Philippines and Latin America. In many cases, Del Rosario was adopted or inherited as a devotional surname rather than descending from a single medieval family line. Because it is a phrase-name, it often appears in records with the particle attached or separated, and it may be used as part of a compound surname.

Fun fact
Rosario is one of the most common Marian titles in the Spanish world, so surnames built from it often signal faith as much as family origin.
