[1] Solomirsky was born as the result of the extramarital affair between Natalya Koltovskaya (née Turchaninova), a daughter of Alexei Turchaninov, and the diplomat Dmitry Tatishchev.
As Natalya' children Pavel and Vladimir were born outside of marriage, the custom dictated that they could not inherit the family name of their father Dmitry Tatishchev.
Pavel Solomirsky served as Polkovnik in the Imperial Guard, retired with the rank of Major General.
[3] At the end of his military career he occupied himself with the family business—running the factories from the Sysert Mining District, which he inherited from his mother.
On July 1, 1835, Pavel Solomirsky married a lady-in-waiting Yekaterina Bulgakova (1811—1880), the oldest daughter of the Moscow post director Alexander Bulgakov.
