Who married Katharina von Querfurt?

Günther XXXVIII de Middelste (Rudolstadt, 1450 – bij Delmenhorst, 19 november 1484) was een Thüringse edelman uit de linie Schwarzburg-Blankenburg. Günther was de vierde overlevende zoon van graaf Hendrik XXVI van Schwarzburg. Günther streed mee in het conflict tussen zijn oudere broer Hendrik XXVII, aartsbisschop van Bremen en bisschop van Münster, en de graven van Oldenburg. Günther sneuvelde tijdens deze strijd. Hij werd begraven in de Dom van Bremen.

Omdat zijn oudste zoon, Hendrik XXXI, nog minderjarig was toen Günther overleed nam zijn oudste broer Günther XXXVI de Oudere de voogdij op zich.

Count Philip II of Waldeck-Eisenberg (3 March 1453 – 26 October 1524 at Sparrenberg Castle in Bielefeld) was count of Waldeck-Eisenberg. His parents were Count Wolrad I of Waldeck and Barbara of Wertheim (b. 1422).

As a younger son, Philip was originally destined for a career in the church, but after his elder brother Philip I died, he left the clergy for dynastic reasons and ruled the County of Waldeck as regent for his underage nephew Henry VIII. In 1486, Philip and his nephew divided the county, with Philip II receiving Waldeck-Eisenberg and Henry VIII receiving Waldeck-Widlungen.

In 1499, a very rich gold vein was discovered in Eisenberg, and after three years there was a long dispute between the Counts of Waldeck and the Lord of Viermund about the mining rights on Mount Eisenberg.

In 1505, Duke William IV of Jülich-Berg allowed Philip II as his governor to operate mines in the districts of Ravensberg and Sparrenberg. Apart from Philip, the board of the mining company included two bailiffs for William IV, representatives of the City of Bielefeld, including both mayors, and a mining expert from Thuringia.

In 1507, he acquired Steffenburg Castle, which had been constructed in Adorf by Curd von Ense in the early 16th Century. He was an ally of Archbishop Albert of Mainz, which was why his was taken prisoner in March 1516 in Padberg by Götz von Berlichingen, who was fighting a feud against Albert at the time. After a long stay in captivity, Philip was released, in exchange for a ransom of 8900 ducats.
