By and large, hereditary surname were formed in Germany when most of the German states were a part of the Holy Roman Empire. At this time, as the population of Europe swelled and travel became easier, people began to encounter others sharing their own name and they avoided confusion by adopting a second name. A common form of surnames found in Germany are those that are derived from nicknames. Nickname surnames were derived from an eke-name, or added name. They usually reflected the physical characteristics or attributes of the first person that used the name. The surname Diemer was a name for a person who was famous among the people. The name Diemer is the German form of the Latin name Theudoricus and it is composed of the Old German word "diot," which in modern German is volk and means people or race, and the Old German word "mar," which means popular, famous, or big. Ditmar is also a local type of surname that comes from Dittmarsdorf in the province of Schlesen. The name Diemer was very popular during medieval times and the family emerged as members of the aristocratic gentry class in the Middle Ages.


In the medieval era, many different cultural groups lived in the German states. There are thus many regional variations of German surnames from that era. Westphalians spoke Low German, which is similar to modern Dutch. Many German names carry suffixes that identify where they came from. Others have phrases attached that identify something about the original bearer. Other variations in German names resulted from the fact that medieval scribes worked without the aid of any spelling rules. The spelling variations of the name Diemer include Ditmar, Ditmars, Dittmar, Dittmars, Dittmer, Dittmers, Ditmer, Dietmar, Dithmar, Dettmer, Detmer, Diemer, Detmers, Dismar, Dismer, Dittmayer, Diesmar, Diesmer and many more.

First found in Germany, where in ancient times the name Ditmar made important contributions to the advancement of feudal society. In later years the name branched into many different houses, some of whom played a significant role in the local social and political affairs of the late Middle Ages.
