Pyotr Petrovich of Russia
Pyotr Petrovich Tsarevich of Russia, named for his father
Son of Pyotr I Tsar (later Emperor) of All Russia (1672-1725) by his second wife Marta Skawronska, who became Empress Yekaterina I in 1725 (1684-1727)
Born: Saint Petersburg 29. Oct 1715
Died: Saint Petersburg 25. Apr 1719
Buried: Alexander Nevsky Monastery, Saint Petersburg.
Note: His corpse was transferred to another church within the Alexander Nevsky Monastery in 1723. This might be the explanation why another child of Pyotr I named Pyotr Petrovich, who allegedly died in 1723, is mentioned in some biographies.
