The surname DIAC originated in Romania, with its earliest recorded use dating back to the 16th century. It is believed to be derived from the Romanian word "diac," which means "deacon" or "clerk." The name likely emerged as an occupational surname for individuals who served as deacons or clerks within the Orthodox Church or in administrative roles.

DIAC can be traced back to various regions of Romania, particularly in Transylvania and the regions surrounding Bucharest. It was commonly found in historical records and documents from these areas during the 16th and 17th centuries.

One of the earliest recorded instances of the DIAC surname can be found in the "Codex Sturdzanus," a collection of Romanian legal documents from the 15th and 16th centuries. The name appears in several entries, indicating its widespread use during that time period.
