Legio V survivors?

[Arminius Primus]

Ave,

Another Balkan conundrum..... One of my jobs is to look after the Minorities here in my small part of the Balkans. One of the more interesting and successful groups are the Vlah.

It is difficult to find information on them from the web. Found a fairly detailed linguistic study about Aroman speakers but other sources are politicized.

Speaking with community representatives, I was priviliged to hear some of their oral traditions. Their name for themselves are <(Tsentse) spelling? > from the latin quinque.

When I asked about that use of the term, I was told that the Vlah within Macedonia are the descendants of the Vth Legion. Hence they call themselves the Vth.

So here come the questions...

Has anyone else heard of this claim?

Does any other ethnic group claim descendancy from a specific legion?

How plausable is this?

Does anyone know of any sources that either refute or support this premise?

Are there any cultural or linguistic markers that could be traced back to a legion heritage?

My head is spinning with a lot more questions but thought that these would spark some discussion.

Regards from the Balkans, Arminius Primus aka Al
