This is interesting. Could you please advise if these results are shared in any DNA website or it can be compared to Big y results to find matches. Thanks
There are also Johnson’s with that Haplogroup (R-CTS4528).
Some came to the USA from Cornwall to Boston MA area in about 1626 AD

Perhaps it entered through there (especially G-L43), perhaps not. By the way, G-L497 predates well Rhaetians and Etruscans, as you know. Anyway, I do agree that it could be among them, in the case it's what you're suggesting. But if you want my opinion, this paper is 7 years old, and it looks outdated in some aspects.
But no. It may actually evidence low diversity: the Corsican men involved would form together a branch not "that" old.

It provides a coalescent time of 13.900 years with standard error of 3.300 for East Tyrol!!
I'm not sure, either, that those age estimations based on STR markers "necessarily" means per se that the clade did originate (or expanded from) there. The following comes from the (much more recent) paper "Prehistoric migrations through the Mediterranean basin shaped Corsican Y-chromosome diversity" (https://journals.plos.org/plosone/ar...l.pone.0200641), just as an example: "Fifteen out of the 17 Corsican G2a2b2a1a1b-L497 displayed a unique Y-STR profile (S4 Table) with an estimated TMRCA of 6867 +/- 1294 years." Do we think that G-L497 arrived in Corsica abt. 7000 years ago? Likely not.
I actually think this TMRCA based on STRs is not even accurate. I mean, if the results are correct and I checked them right, all these Corsican G-L497 men would have Y-GATA-H4=12, and sixteen out 17 would have DYS461=10, two results uncommon among G-L497 men. What a coincidence it would be.
Well, G-L497 does have a relatively high frequency around that part of Alps and surroundings, apparently, and Berger's map catched up that, as others - including Eupedia's. However, I'm affraid G-L497 highest SNP diversities would be somewhere else, and even the STR diversities suggested in the paper "Reconstructing the genetic history of Italians: new insights from a male (Y-chromosome) perspective" don't falsify this notion.

There is some frequency in there, but I'm affraid the evidences are of low diversity in the East, actually. G-L42, for example, is the most frequent in Balkan as a whole, but most of them by far belong to G-Y128028. The major expansion would have happened from an area more to the West, probably not far from those where STR diversities supposedly peak. Where the MRCA lived may be another story, at least according to ancient DNA.
