Gallic appearance

[Aryaman2]

no, they wouldn't, the french are mostly franks, or other gemanic amalgamations, as comerus said, and probably bear little resemblance to the guals. I think the Welsh and irish might be the closest we have to an old celtic type ethnicity, especially since many of the guals migrated to ireland in the 1st c. B.C., and settled entire portions of it. It seems to be borne out by the fact that the coin looked almost identical to members of my family, primarily welsh, and irish, with a very small portion of german and cornish as well.

Again, Im sure not all gauls looked alike at all, there would be some in the north looking germanic, and probably some in the southern part with some italic, or different bits and pieces.

Genetic research has shown there is an haplogroup, HG1, present 99% in original Western Irish population, that is considered to be predominant in prehistoric Western Europe. Today it is just about 60% in France, so modern French doesn´t exactly descend from ancient Gauls, not completely at least.
On the appearence of Gauls in classic writers, some points could be made
1) According to Kristian Kristiansen anthropometric studies show Gallic upper class (noblemen and their retainers) to be 5-10cms taller than average Gallic population
2) Add to that taller warriors were usually placed in the first rank, and you get a rather impresive line of battle of tall barbarians
3) Even if only a small part of Gallic warriors were blonde, they were probably noticed and remarked as characteristic, id est, different from average roman soldier. The spicatum hair also could have helped to get the impression.
