Adelmo is of Germanic origin, derived from the Old High German elements 'adal' meaning noble, and 'helm' signifying helmet. It was popularized through the Italian form Adelmo, which is attributed to Saint Adelmus, a 7th-century bishop of Bergamo in Italy. The name gained prominence during the Middle Ages due to his veneration as a saint. Today, Adelmo is still recognized as a traditional name in Italy and other regions influenced by Italian culture.
"Adelmo was quite popular between 1929 and 1940 with a total of 13 children named thus."
