Well. I'm not Celtic, I'm Scandi and I can tell you that there are many organizations that link Norway and America. There is the Norwegian American Genealogical Association, the Norwegian-American Historical Association at St. Olaf College, the Norwegian American Genealogical Center and Naeseth Library, Sons of Norway, and the Vesterheim Museum in Decorah, IA. There are Syttende Mai celebrations, Nordic Fest and all types of gatherings with Nordic theme that happen in America, mostly midwest and northwest. You can also join Bygdelag. Bygdelag correspond to what fylke (or county) you ancestors came from in Norway. I have recently traced several lines of my ancestry back to their farms in Norway. And there is the Bygdelagenes Fellesraad
the organization that encompasses all of the bygdelag together. All of the bygdelag and the fellesraad have annual meetings. Usually there are classes and speakers on rosemaling, hardanger embroidery, bunads (traditional Norwegian dresses) traditional dance and music, Stave style churches, mythology, the American frontier experience etc. etc. It is my impression that although these subjects and organizations might not be particularly popular, the people that do get into it, really get into it. They are passionate and when you get bitten by the genealogy bug you keep coming back.
SO...these things are out there! They are NOT DEAD! I'm not sure if other groups such as Celtics are this organized here in America or not. I wouldn't be surprised if they are. If you want a real angle, I would ingratiate myself into some of these organizations and go from there. It might sound boring and you might have to socialize with old people, but this is the form that heritage takes. It's kind of old fashioned. It also strikes a good balance between "mainstream acceptability" and authentic heritage.
I see a real desire and interest in European heritage bubbling just below the surface everywhere! It's just waiting to be unleashed! Do some searching on the internet, put your nose to the grindstone, and ingratiate yourselves into this kind of thing.
What do you have to say to that, Dinaric?
