[citation needed] Polish historian Marian Karol Dubiecki [pl] suggested the connection of the name of the fortress with the Polish roots linking it with the surname Kociuba, [1] an opinion criticized by Vasili Nadler [ru].

[2] An early mention of a "port Kaczubyeiow" dated 1415 is given by Jan Długosz in his Historiae Polonicae.
