Family Name Krust

It was customary in earlier times to refer to persons only with a nickname, since the beginning of the 12th century there has been an increased and then increasingly regular personal name with nicknames. From occasional additions created consistent epithets and when these nicknames were inherited, created the family names.
The current family names KRUST and KRUEST appear in the two original forms Crust and Krust. Evidence for the spellings with G are late and isolated (eg Gundelfinger sub-branch), with a separate surname Grust can be found in northern Germany, but has nothing to do with our family.
Other proven spellings of the surname are: Chrust, Croust, Krusst, Krußt, Kruscht and Khrusht.

There are three possible interpretations of the meaning of the surname, of which the first two are considered possible and the former are given preference:
1. crust = (bread) bark, crust, scab
Thus the name comes from the broadening with Indo-European root "kreu" [coagulum (originally from the blood)], which has also been defeated in Latin as crusta [bark, crust, scab].
2nd crust = goods for the army, equipment
So it would be a reinforced with "k" form of early modern high German "rust" [equipment, household effects]. The previous Öschelbronn family tradition refers to the name of the man who had either personally many items of military equipment, or who managed or kept such for the community. Krust then means something like "Schirrmeister". In Swabian dialect, there is still the word crust, which originally designated the war items, but today is used for all sorts of nonsense.
3. 3. In the Slavic languages ​​there is the root 'Krust', which is found there in person and place names.
The third derivation is eliminated because the name has not developed in the Slavic language area. The second interpretation, which comes from the family tradition, is closely related to the Swabian area, but as the article "The Origins of the Krust Family" has shown, the name probably originated in the Bretten area. Furthermore, Hans Krust in the pattern list 1553 as a philistine with armor, which has not used in the war called. Thus, the first meaning is the most probable. The first name bearer was either in some connection (e.g., profession, nickname) with bread crust or had a physical trait associated with "crust."
In the course of the 19th century, even at the request of the authorities, the spelling of surnames became established, and our surname became KRUST.

In 1867 Georg Friedrich Krust emigrated from Blaufelden to the USA and founded the family branch KRUEST by a small change of his family name. This may be due to the fact that the u (see left) in the old German manuscript was provided with a roof and was so easily confused with the ü (see right).
So today we find the two surnames KRUEST and KRUST.
