Pyotr Aleksandrovich Gruzinsky

Prince Petre (პეტრე), known in Russia as the tsarevich Pyotr Aleksandrovich Gruzinsky (Пётр Александрович Грузинский) (26 April 1857 – 3 February 1922) was a Georgian prince (batonishvili), a descendant of the Kartli-Kakhetian branch of the Bagrationi dynasty, the former royal house of Georgia. Petre was the son of Prince Alexander Gruzinsky.

Prince Petre married Tamara Dekanozishvili (1897–1977, who was born into a family of minor parochial noblemen) at an unknown date by the historians (certainly during the war turmoil). Tamara Dekanozishvili, who was 40 years his junior, was firstly [or secondly] married to Aleksandr Timofeevich Oboladze (1884–1923).

They had two sons:
 * 1) Konstantin (1915–1939).
 * 2) Petre (28 March 1920 – 13 August 1984).
