Prozorovo
Prozorov, in the country north of the Mologa and Volga, is recorded from 1408. From that year until 1460 it was the center of the appanage principality of Prozorov, one of the small princely domains of the upper Volga region. Its ruling family belonged to the line of the princes of Mologa. After Moscow absorbed Mologa, members of that family moved to Moscow and became known as the princes Prozorovsky and Shakhovskoy.
