Herman is a masculine given name, from an ancient Germanic name consisting of the elements harja- "army" and mann- "man".
[2] It regained popularity in the English-speaking world in the 19th century, particularly in the United States amongst German Americans.
The conflation of this element with the name Herman may indeed date to the medieval period, via variant forms such as Ermin, Ermen, Erman, Ermanno, feminine Ermina, Ermana, Hirmina, Hermena.
[4] The name Herman was popular in the United States during the late nineteenth and early twentieth century, consistently ranking between 55 and 44 throughout the 1880–1914 period.
Beginning with World War I, the name's popularity entered a steady decline for the remainder of the twentieth century, falling below rank 1,000 in the year 2000.
