Ostromir
Ostromir ("Остромир" in Russian; Christian name - Joseph) (died c. 1057) was a statesman, voivod and posadnik of Novgorod in 1054-1057 and probably for some decades previous.
Ostromir is known from the first Russian dated book, the Ostromir Gospels (or Ostromir Codex), which he commissioned from his scribe Gregory.
The chronicles record that Ostromir was the father of Vyshata and the grandfather of Yan Vyshatich.
The Ostromir Gospels names his wife as Theophana, viewed by Andrzej Poppe as a daughter of Anna Porphyrogeneta and Vladimir the Great.
Another popular speculation posits Konstantin Dobrynich as the father of Ostromir.
According to the First Sophia Chronicle, Ostromir died in 1056 during his military campaign against the Chudes.
It is highly unlikely, however, since the afterword to the Ostromir Codex clearly states that he was still alive in 1057.

Konstantin Dobrynich
Konstantin Dobrynich (died 1022) was an 11th-century posadnik of Novgorod.
According to the Novgorod chronicles, he was the son of Dobrynya and wielded great influence at the court of his own cousin, Yaroslav the Wise.
The time at which he became posadnik is uncertain, as are the circumstances.
In 1018, he is said to have destroyed the boats which Yaroslav intended to use for fleeing to Scandinavia from his brother Svyatopolk I. Konstantin persuaded Yaroslav to continue his war against Svyatopolk, helped him muster a new druzhina and regain the Kievan throne.
Several years later, he fell into disgrace, for reasons unknown, fled to Rostov and was eventually assassinated in Murom at the behest of Yaroslav.
Historians tend to view Konstantin as a leader of an anti-Varangian party in Novgorod.
His conflict with the Varangians is sometimes given as a reason for the promulgation of the earliest part of the Russkaya Pravda.
On the other hand, the chronicle's information about his career may have been biased, if Konstantin indeed was the ancestor of the chronicle's co-author, Yan Vyshatich, as many historians speculate.
