Previously, I had wondered if this guy was a Spaniard. I'm pasting what Eurogenes Alberto came up with, although I don't know what methodology or tool he's using (otherwise I'd comment on everything)
Everything looks pretty square for a guy from Budapest...... except for the Iberia_Southwest_CA 48.44%!
How about another one.

This is one of two brothers that have the same mother in Alburg, Bavaria, Germany. Maternally H1e1a. Since CWC is excluded from these analysis (which is fine), we get inflated Yamnaya, Ukraine and Sweden MN, since it wants to find a big chunk of CW that isn't there. This small cemetery is described by Heyd as belonging to the later begleitkeramik phase, so we should have a trickle of weird Balkanesque stuff that became increasingly prominent in those Csepel communities early on. Check.
Again in this example, we're poking around at SW Europe in the mid to low teens. And what is the inspiration for a decoration such as this?
Most of these folks are within a few generations of being mixed so it's especially important to look at individuals and context.
Anyhow, Iberian (or wherever) is all over the place, albeit very unevenly distributed if real. Hopefully someone can try Hegenheim again.
