Wiesztortowicz of Podbrzezie and Bakszty in the Grand Duchy of Lithuania
Research which was done so far proved that on the territory of the Grand Duchy of Lithuania existed at least several families named Wiesztort or Wiesztortowicz (Westortowicz). Wiesztortowicz is a patronymic name. Both name variations appear in the original documents. Most of the found Wiesztort/Wiesztortowicz belonged to higher class called boyars however there were found also families belonging to town people or peasantry.
Hanko Wiesztortowicz was the first known member of the family. As a witness he was mentioned in a document issued in Łyntupy and dated on 1459. This document referred to Andruszko Dowgirdowicz, owner of Świrany and Łyntupy, who made donations to a church in Łyntupy. Besides Hanko the document mentioned also other witnesses as Sudywoj Wolimuntowicz, Castellan of Vilnius and Wieżgajło, koniuszy/equerry and ciwun of Vilnius.
Hanko probably had a son named Jacko. In 1472 he was a witness to a document in which kniaź Sieńko Romanowicz Świrski donated some estate to the church in Świr. Jacko Wiesztortowicz wrote a will which was issued in Podbrzezie in 1484. He made donations to the nearby church in Mejszagoła and gave to his wife Anna estates in Podbrzezie and Bakszty as well. There were several places called Bakszty but the most probable is the one which was located between Łyntupy and Świr. In the same will Jacko mentioned several people who had owned him money. Some of them belonged to the highest Lithuanian social class at that time. The total amount of money mentioned in the will is 156 kop of the Prague Cents/grosz. The first executor of his testament was kniaź/prince Daumont Butwidowicz Świrski.
The third generation of the investigated family is represented by Jan Wiesztortowicz. He was probably a son of the above mentioned Jacko. He appeared in two documents dated on 1501 and 1503. Those two documents concerned different donations to the church in Podbrzezie. Jan is mentioned there among other local nobles who gave land and serfs to the church. Personally Jan donated a field of 1.5 hectares and a meadow calculated as six wagon-driving of hay.
It is hard to say whether next generation of the family is mentioned in the 1528 Lithuanian Enrollment List. The family could migrate to other territories. There is a high probability that above mentioned Hanko Wiesztortowicz was a brother of Miszko Wiesztortowicz a Lithuanian łowczy and namiestik Deputy of Słonim. Miszko started the most well-to-do Wiesztort/Wiesztortowicz family line of the Sulima coat-of-arms which existed in Ruś/Rus. The main estate of this family branch was Sielec (near the town of Bereza) and Krzemień in Podlasie.
