Johannes
A Latinized personal name meaning “John,” sometimes preserved as a surname in records and modern usage.
The #9,412 most common surname in the United States (2010 Census) — about 1 in every 89,362 Americans shares it.
Etymology
Johannes is the Latin form of John, ultimately from Hebrew Yôḥānān, meaning “God is gracious.” In medieval and early modern records, Johannes often appears as a given name in Latin documents, but it can also become a hereditary surname where a person or family retained the Latinized form. As a surname, it is therefore best understood as a name derived from the personal name John rather than from an occupation or place.
History
The excerpts mainly show Johannes as a Latinized forename in medieval records, which reflects how scribes wrote names in formal documents. In surname use, forms like this are usually connected to the widespread Christian name John and may have been preserved in clerical or immigrant contexts. The modern surname is comparatively uncommon in the United States, which fits a name that is more often encountered as a personal name or as a learned spelling.
