I think that generally speaking real changes in the genome (autosomal dna) are the result of mass folk migrations. However, it's certainly true that individuals may have unknown ancestors in their family tree from some much smaller migration.
At the same time, any actual autosomal trace of some specific individual from a distant place could disappear within two-three hundred years of admixture solely with "natives". Depending on the individual case, person X might have absolutely no dna even from a great-great grandparent.
That's why although I have a very extensive family tree I'm not very interested in most of the people on it. I may have none or extremely little of their "specific" dna at all, i.e. no IBD sharing with them, although in broad terms we share ancestry from the same clusters of people.

Btw, no reason you can't discuss Ashkenazi genesis if you're interested. Just go to the thread to which I linked.
I am mostly Sephardi, Canaanite. My Ashkenazi could be 1.2% Mediterranean Islander from DNALAND says Cypriot, Sicilian. That 1.2% is only bit I show among all DNA tests. This goes parallel with my extremely low 1.11 Italian in K36. My Sephardic ancestors would have mixed potentially with Romaniote, Italkim, Ashkenazi.
