Elbert is of Germanic origin, derived from the Old High German 'Adalbert', which means 'noble and bright'. It was popularized during the Middle Ages through Saint Adalbert, a missionary bishop who lived in the 10th century. The name Elbert has been used in various forms throughout history, such as Adelbert or Albert, but it remains relatively uncommon today. In literature, there is a character named Elbert in Mark Twain's 'The Adventures of Huckleberry Finn', adding to its cultural significance.
"Elbert seems to have been a popular name from the 1920s to the 1950s, with peaks in popularity around the mid-1920s and late 1940s to early 1950s. After 1957, its usage significantly decreased."
