According to them, Kondratii Ivanovych Kobyzewicz (Kobyzenko), a Cossack of Helmiaziv of the Pereiaslav regiment, supposedly acquired the nickname of Lyzohub.

[4] Kondratii Lyzohub supposedly had a daughter named Christiana, and sons: Yakiv, Ivan and Klym.

[2] The researcher Erwin Miden, a post-graduate student of the Chernihiv National Pedagogical University, has debunked the myth of the Lyzohub family's descent from the Kobyzewicz clan.

He has also showcased in his article on Colonel Ivan Lyzohub, that his Polish nobility was fabricated by his descendants in the 18th century.

[8] As the colonel of Chernihiv, Yakiv Lyzohub took over the lands of his predecessor, H. Samoilovych, including the estate of Sedniv that had become the family's main seat.

A connection to the Lyzohub family allowed Afanasii Yanovsky to pursue military career.
