Korniaktos, a Greek, was born in the city of Candia (today Heraklion) on Crete in 1517. He moved to Constantinople at a young age where already in 1540 he became a wealthy merchant. Later he moved to Moldavia where he lived for the rest of his life. Some time in the 1560s Korniakt settled in the city of Lwów (now Lviv, Ukraine) where he took over a business of his older brother Michael. Already at the time Moldavia in Lviv was closely associated with Walachia. The King of Poland Sigismund II Augustus granted him official title of nobility on February 12, 1571 as szlachcic Konstanty Korniakt, also awarded a number of other privileges, thereby establishing the Krucina coat of arms.

Konstanty Korniakt dealt with international trade, especially from the Ottoman Empire and countries in Germany. He became a merchant and traded in wine, cloth, cotton, honey, hides and furs and soon became very wealthy, even lending money to the kings of Poland including Sigismund II Augustus, and other noble families.
Korniakt was a patron of architecture and built a magnificent house near the market, which later was rebuilt by John III Sobieski and is now known as the Korniakt Palace. He also expanded the Wallachian church and funded its famous tower. He was an ardent follower of the Orthodox Church and defended its interests maintaining friendly relations with other Christian denominations.
Around 1575 he married Ruthenian noblewoman Anna Dzieduszycka h. Sas, and soon had children. His sons were Alexander, Constantine (father of Captain Charles Francis) and Michael Korniakt, his daughters were Katarzyna, Anna (married Jan "Gratus" Tarnowski), Sophia (married Abraham Hubert) and Catherine (married Aleksander Chodkiewicz and after his death the governor of Belz, Duke Konstanty Wiśniowiecki).
Soon after his death in 1603, all of his children converted to Catholicism and eventually were polonized. His son subsequently sold part of his estate and land in Lwów, and his brother Alexander Korniaktow left and moved to the property he inherited from his parents in Przemyśl. He was owner of three residences in the villages Sośnica, Złotowice and Białoboki, the latter being chosen for the family. In 1610 the construction of the castle began.

This second redaction appeared no earlier than 1589, as wealthy Greeks began to join the confraternity at a later date, once it had expanded its activities. Korniakt was actually the wealthiest man in Lviv: he traded in Eastern, Western, and local goods, collected customs duty on behalf of the king, and owned a number of villages.
