Фетисов Павел Прохорович
brother of great-grandmother Александра
The name and relationship are recorded in a handwritten pedigree from Valentina's memory; no dates.
The patronymic is indicated by the father (Fetisov Prokhor).
The first Paul (1889) died as an infant - separate card; this Paul from Valentina's genealogy was probably born later; its metric was not found.
