Forgot about the Vikings. There is a lot of Viking ancestry in the UK. I actually lived in Norway for a wee while, and still have one or two relatives there. Never told them about the German connection though, as I valued my life! Actually, my German connection was only for a couple of generations. They were Esslers from Mecklenburg, and made their living in Ulster as cattle dealers/drovers. Not people to be messed with, and they and my Walkers had a "mafia" of outposts along the drove roads in County Antrim.
All of my considerable Irish ancestors were from the former province of Ulster (the original 9 county Ulster, and not the current "Northern Ireland" version).
Eclectic musical tastes have been a part of my life for a very long time. A few years ago I abandoned the accordion (again) to go back to playing Greek bouzouki. My sister lives on Crete and I decided to rekindle my interest in that instrument. Never lasted long, as the only people who can play bouzouki well are all Greeks (thought I'd have that worked out at the age I was, but that's just the way I am).
Over the years I have played harmonica, guitar, trumpet, violin, penny whistle, mandolin (my grandmother was a great player), Turkish saz, Greek bouzouki, Persian lute, charango, ronrroco, requinto, pan pipes, balalaika, clarinet, and various other folk related wind instruments. Managed to get tunes out of all of them, then I discovered the accordion (too late) and they all became redundant, with the exception of the guitar which I still play.
Maybe you can't get more eclectic than that, but I bet there is probably somebody who can.
