The family came to prominence in the early 18th century at the court of the Georgian king Vakhtang VI of Kartli. A family legend traces their origin to Greek choristers who accompanied the Byzantine princess Helena Argyre into Georgia upon her marriage to King Bagrat IV in the 11th century. Members of the family were privileged to serve as archpriests at the Georgian court and as hereditary keepers of the Okona Icon of the Mother of God. Garsevanishvili family was included in the list of nobles of Georgia in 1860 in the so-called "Barkhatnaia Kniga" published in Saint Petersburg.
They followed Vakhtang VI in his Russian exile in 1724 and entered the Russian service, adopting the surname of Gersevanov (Garsevanov). They were granted estates in the governorates of Poltava, Kharkov and Yekaterinoslav. Those who remained in Georgia were reconfirmed among the nobility by a charter of King Erekle II in 1788.
The notable members of the family were also Mikhail Nikolayevich Gersevanov (1830–1907), an engineer who supervised numerous road-building projects in the Caucasus; and his son Nikolay (1879–1950), also an engineer specializing in ground mechanics.
- The Okona icon, revered as miraculous, had been preserved at the medieval Georgian monastery at the village of Okona (ოქონა). This ivory, silver-covered triptych, which according to a legend was brought by Princess Helene from Constantinople, was confiscated by the Soviet government in 1924 and ceded to a museum in Tskhinvali from where it disappeared during the War in South Ossetia in 1991. The icon was discovered at the Christie's auction office at Geneva in 2001 and returned to Georgia upon its government’s request in 2004. It is now on display at the Georgian National Museum.
