Urnfield cultures were primarily a religious movement. There are different cultures below that large cultural phenomenon of Urnfield and this includes Proto-Celts, as a branch of the Tumulus culture which was converted by the Carpathian basin people. These Carpathian basin people which practised cremation before the Tumulus culture (Italo-Celts) was likely the Proto-Thracians and dominated by E-V13.
MIddle Danubian Urnfield group (= descendants of Danubian Tumulus culture people = R-L2), Proto-Villanovans (= unclear, but probably related to the Venetic people and influencing Etruscans and some Italics), Lusatians (= unclear, but they seem to have had a lot of I2 and R-L51 too), South Eastern Unfield groups (primarily Gáva-related at the LBA = likely E-V13 and Proto-Thracian).
To the North West in Western Germany-Eastern France were different Urnfield groups and those likely were Pre- or Proto-Celtic.
It is absolutely evident that the Tumulus culture people didn't disappear, but just converted when coming into contact with the Carpathian people along the Tisza, where they halted in the MBA-LBA (most Eastern group being Egyek-Carpathian Tumulus culture group). From the influences of the Tumulus culture emerged in the East Gáva and from the opposite influences to the West the other Urnfield groups.
We therfore deal with very different ethnolinguistic groups, even non-IE (like Etruscans) in the Urnfield sphere.
