Italy, especially the area north of the city of Rome, has also had a history of heavy Germanic settlement. Germanic tribes such as the Visigoths, Vandals, and Ostrogoths had successfully invaded and sparsely settled Italy in the 5th century AD. Most notably, in the 6th century AD, the Germanic tribe known as the Lombards entered and settled primarily in the area known today as Lombardy. The Normans, a partially Germanic people, also conquered and ruled Sicily and parts of southern Italy for a time.
We present the analysis of mtDNA control-region sequences in samples of the Kazakh, the Uighurs, the lowland Kirghiz, and the highland Kirghiz, which we have used to address both the population history of the region and the possible selective pressures that high altitude has on mtDNA genes. Central Asian mtDNA sequences present features intermediate between European and eastern Asian sequences, in several parameters-such as the frequencies of certain nucleotides, the levels of nucleotide diversity, mean pairwise differences, and genetic distances. Several hypotheses could explain the intermediate position of central Asia between Europe and eastern Asia, but the most plausible would involve extensive levels of admixture between Europeans and eastern Asians in central Asia, possibly enhanced during the Silk Road trade and clearly after the eastern and western Eurasian human groups had diverged. Lowland and highland Kirghiz mtDNA sequences are very similar, and the analysis of molecular variance has revealed that the fraction of mitochondrial genetic variance due to altitude is not significantly different from zero. Thus, it seems unlikely that altitude has exerted a major selective pressure on mitochondrial genes in central Asian populations.

Blonde hair alone isn't evidence there were romans there. I mean, everyone accepts the European appearing mummies found in china as real:
In the late 1980's, perfectly preserved 3000-year-old mummies began appearing in a remote Chinese desert. They had long reddish-blond hair, European features and didn't appear to be the ancestors of modern-day Chinese people. Archaeologists now think they may have been the citizens of an ancient civilization that existed at the crossroads between China and Europe.
