Marinus is a name of Latin origin, derived from the word "mare," which means sea. It was popular among early Christian saints and martyrs, including Saint Marinus, who was a bishop in the 4th century. The name Marinus has been used throughout history, particularly in countries with strong Roman Catholic influences, such as Italy, the Netherlands, and Belgium. Today, it is still considered a classic and timeless name choice for boys.
"Marinus saw a peak in popularity during World War I, with the highest number of births occurring in 1916 (16). However, it has remained relatively uncommon overall, with fewer than 10 births per year in most years since then."
