The paper deals with the oldest place, ethnic and personal names from Pannonia and Dacia (I-II AD), as well as from Circummaeotic region (III-IV AD), having Common Slavonic features. Common Slavonic place names and hydronyms mark the oldest areas of Slavonic language in Pannonia, Poland, Volyn' and Podonie. The distribution of early Slavonic place names correlates with regions of large Slavonic communities of Oseriatae (Pannonia), Venetae (Poland), Sclavini (Volyn') and Antae (Podonie) in the I-VI cc. AD. The movement eastwards changed into westward migrations in 375-453 AD. The empire of Hunni and its movement from Circummaeotic regions to Pannonia correlates with the Old Bulgarian legend of migration and settlement of five brothers, sons of Kubrat, and their tribes (Chronicle of Theophanes and Breviarium of Nicephorus). At the same time late Roman historians and Bulgarian ethno-genealogical legend describe inter-regional migrations of Slavonic communities and their settlement in the countries of traditional habitation till today.
