Nicolaus Seidlitz von Lazan

The von Lazans are a Bohemian-Silesian branch of the Seydlitz family that used the arms Kurzbach (Korzbok in Poland).

Records of this family are extensive but confusing because of the repetition of the same names within generations as well as from generation to generation, and because of conflicting information in the sources.

The Polish branch of the family is descended from Jan Korzbok, who appears to be the son or grandson of Nicholaus.

Jan is an heir of Nicholaus and the son of Jan/Hans. Nicholaus is a brother of Cunneman and a Johann and a father of another Jan/Hans/Johann. Hans/Johann is listed in several sources as the brother of Cunemann and the father of Johann von Lazan. Cunemann is explicity identified as the "Onkel" of Johann von Lazan in at least one source, and Jan is identified as a nephew (perhaps great nephew). Another source states that Johann von Lazan was the son of either Cunemann or his brother Hermann.

As an owner of Lazan, Jan/Johann is presumably an heir of Cunnemann's father Gunzel. Johann is variously identified as Cunneman's brother, son, nephew (son of his brother Hermann, Hans, or possibly Heincz). However, other accounts identify Nicholas von Seidlitz as his father and note that Nicholas married the daughter of Vincent, Warden of Gniezno and Governor (Wojwode) of Poznan and Great Poland (Wincenty z Krępy herbu Doliwa, Wojwode 1371-1386). A number of sources list Nickel/Nicolaus/Claus as a brother of Cunneman and/or the father of Johann.

Johann (Jan Korzbok) apparently solid his holdings in Silesia in 1360. On May 25, 1366, Nicolaus Cordbok purchased the village of Swieciechowa, according to the official records of Poznan. His father-in-law apparently arranged the sale over the initial objections of the Abbot Johann Warmul. Jan Korzbok appears as the heir of Swieciechowa in later records.

After Nicolaus and Johann left Silesia/Bohemia, their claim to Lazan passed to other members of the family. Tamme/Themchin von Lazan appears in the records, along with Gunczel.

Title to Lazan eventually passed to Heinrich Lefl von Lazan (c. 1370-1420). He was a royal courtier, Chancellor/Treasurer of Bohemia, Military Governor of Breslau, and friend and protector of Jan Hus. Heinrich Lefl offered Hus refuge at his castle at Krakovec in 1413-1414. According to some sources, Heinrich Lefl requested the promise of safe passage for Hus to the Council of Constance. (After he arrived in Constance, Hus was tried for heresy and burned at the stake.) Heinrich Lefl remained loyal to the Crown and was killed in battle by the rebellious Hussites, who buried him with honors because of his relationship with Hus.
