Since traces of the presence of the Proto-Bulgars on the territory of Ukraine were left by the in many place names, an attempt was made to find matches also in anthroponimics. Possibility of the existence of the Ukrainian surnames Bulgarian origin is confirmed by such fact. The name of the village of Gavarechchina in Lviv Region has a clear Bulgar origin, as it is connected to the common village handcraft of black pottery. The surname Bakusevich is typical for this village and it also has Bulgarish roots because old Chuvash male names Pakkuç, Pakus, Pakăs are recorded. The surnames Bakus, Bakusevich or Bakutsevich are found also in the villages of Kimir, Ushkovichi, Chupernosov, Nedilyska in Peremyshlyany district, Lviv region, where the existence of Bulgar settlements can be confirmed by archaeological data (Cherepin-Lagodiv group of sites). Incidentally, the names of the first three above-mentioned villages are also explained by means of the Chuvash language. Obviously, Ukrainians took the name Backus from the Bulgars still in For-Christian times, and it was an additional person identifier after spreading Christian names. Later it or derived from it Bakusevich Bakutsevich were recorded as a surname. The explanations of the meaning of these noted names are is absent in the Chuvash dictionaries, but maybe, they oroginated Chuv. pak "swiftly" or pakka "to thrash, beat" in conjunction with the affix uç. This affix, just as aç eç ere used to form nouns. Thus, we can be sure that some other Ukrainian surnames exist since prehistoric times, as well as names of villages in which they occur.

As far the proposed etymologies correspond to the truth cannot be appreciated without additional historical evidence of the nationality of the ancestors of carriers of specific surnames and they are unlikely to appear once. Therefore, they themselves do not prove the presence of the Bulgars in a certain territory of Ukraine, we have other convincing data for this. Ukrainian surnames of Bulgarian origin are additional material for the study of historical phonology of the Turkic languages. Together with the toponymy, anthroponymy establishes a certain chronological framework for the existence or transformation of the distinct sounds of these languages. In addition, a comparison of Ukrainian and Chuvash anthroponymic systems (similarity in semantics, structure, creation) will provide concrete material for studying the spiritual culture of our ancestors and establishing patterns of anthroponymy in prehistoric times and at the same time will help establish at least an approximate time of the emergence of individual surnames, which is also important.
