Fedoseyevich
Fedoseyevich is a patronymic, a type of name derived from the father's given name. Specifically, it indicates that the father's name was Fedosei. In Russian naming conventions, patronymics are a crucial part of a person's full name, following the given name and preceding the surname. They are used in formal address and as a distinguishing element within a family. The ending "-evich" signifies that the father is male. Therefore, Fedoseyevich literally translates to "son of Fedosei." This patronymic would be used by individuals whose father's given name was Fedosei. For example, if a man's father was named Fedosei Ivanovich Petrov, the man might be addressed as Ivan Fedoseyevich Petrov. Similarly, a woman whose father was Fedosei Ivanovich Petrov would be addressed as Maria Fedoseyevna Petrovna. The use of patronymics remains common in Russia and other cultures that follow similar naming traditions, serving as a marker of respect and familial connection.
