Despite this connection, the Vučedol is likely not just the ancestor of Illyrians, but also Daco-Thracians. E-V13 remains largely obscure until after Vučedol, and would have been assimilated by IE-Speakers descended of the Vučedol somewhere in Banat during the Broomstroke Horizon period. This Horizon formed primarily out of the Mako variant of the Vučedol Culture and expanded into Oltenia and Transylvania, becoming the basis for the Verbicioara, Vatin, Maros, Wieternberg and Tei cultures. The Vatin culture would later evolve into the Belegis Culture and the Channelled ware Horizon, spreading E-V13 and Daco-Thracian.

Unfortunately, all of these groups cremated, so we can only speculate about their ethnicity using archaeological origins and influences.
