There's in total six U5a2 samples from Mesolithic France and Germany, one from Mesolithic Russia, and one from Mesolithic Sweden. See [cannot link]
As far as I know most modern European U5a2a belongs to a single subclade and this sublcade (probably)originated in Russia and spread into the rest of Europe 5,000-4,000 years ago. So, most U5a2a came into Europe with the "Steppe"(coast of Black and Caspien sea and land just north of it) migration that brought Y DNA R1 and probably Indo European languages. Gail told me once that there are also other types of U5a2a in Europe which have (non-Russian)local Mesolithic origins.
That's the distant big picture origin of your maternal line(mtDNA). Of course it has a long history after that and before it.
