Thanks for that history lesson on events close to my town of birth. :)

Gunzelin, Margrave of Meissen
Gunzelin of Kuckenburg (c. 965 – after 1017) was Margrave of Meissen from 1002 until 1009.
He was the second son of Margrave Gunther of Merseburg (c. 949 – 982), thereby the younger brother of Margrave Eckard I of Meissen, and possibly half-brother (or brother-in-law) of the Polish prince Bolesław I the Brave. Gunzelin held allods around Kuckenburg Castle (in present-day Obhausen) near Querfurt.
After the death of his father at the 982 Battle of Stilo, his elder brother was enfeoffed with the Margraviate of Meissen by King Otto III. In 1002, following Eckard's failed attempt at the throne in the German royal election and his subsequent assassination, Bolesław occupied Meissen, but the new king, Henry II forced him to leave it and accept the March of Lusatia with the adjacent Milceni lands instead.

This is weirdly specific. But I like it :)
