The following description has Antonie Hamester, born Kock, made in 1951 as a student.
The district of Stormarn belongs with Dithmarschen to the very few administrative districts of the present, which have preserved the name of an old Volksgaues of ancient times to this day. The today's circle originated only in the year 1867 after the introduction of the Prussian administrative order. It includes in its northern part areas which until then were not counted as Stormarn. On the other hand, especially in the West, throughout history vast areas of the Gau have been incorporated differently and have received different names in their special development. The name "Stormarn" refers to the years 1867 for centuries on the three "stormy" offices Trittau, Reinbeck and Tremsbüttel as well as the still existing Teststei Stormarn.
Relatively late, Stormarn emerges as a distinct, circumscribed landscape from the darkness of the lore. While we hear of Dithmarschen, at least as early as the days of Charlemagne, we hear of Holstein and Stormarn, on the other hand, only at the end of the eleventh century learn more about the historian of the North, Adam of Bremen. Adam of Bremen reports:
The North Elbe Saxons disintegrate into 3 peoples. The first are on the North Sea the Dithmarscher (Tedmarsgoi) and their mother church is in Meldorf; the second are Holsten (Holcetae), named after the woodcuts near which they live. The third and noblest are called the Stormarri, because this people is often moved by storms of unrest.
Thus Stormarn was also settled at that time by a part of the prominent Saxons. Almost 150 years from the middle of the 12th to the end of the 13th century, the time of the great settlement movement in our country lasted. Around 1300 in Stormarn, Ostholstein and Lauenburg essentially the settlements that we know today. Due to the former settlements, the existing forest areas were increasingly cleared and the cleared land made arable. The two large and significant forests remained: "the Saxon forest and the Hahnheide".
The eastern part of Stormarn is bounded by the border wall "Limes Saxoniae". Linked to this are the innumerable castles built in Stormarn in earlier centuries; Very often one speaks here of robber baron castles. Thus, in this respect, Stormarn is quite verifiable, especially historically.
As far as the location of the country is concerned, Stormarn has been called all land between Stör and Trave, Bille and Elbe. So these rivers can very roughly serve as the border of the Stormarnland; but in this judgment one has followed the natural limits more than the historical ones. Even the pre-historical researcher Russ considers that the Wilstermarsch must be counted as part of Stormarn; but such an extent has historically been undetectable. So today's district covers the area between Hamburg and Lübeck, bounded by the districts of Lauenburg, Segeberg and Pinneberg. In the south of the district of Stormarn we find a pretty graceful landscape; because between the towns of Großensee, Lütjensee, Trittau and also in Dwerkathen there are a number of lakes, ponds and moored sinks in the middle of this end morainic landscape. Also extend here most of the forest areas of the district and the Hahnheide and Sachsenwald, so this part is publicly known as the "stormarnsche Switzerland". In the southern part of Stormarn, surrounded by forests and lakes, in the valley right on the edge of the forest of the Hahnheide, on the north bank of the Bille, is the Village of Trittau.
