I love the Arberesh dances and way of life.
I was, as you'd expect, visiting the Evangelical community each time. On the third visit two other chaps were with me (one English, one Kosovar), and we also visited the Orthodox bishop and had a fairly long session with him. He gave me a gift of two CDs of Arbëresh singing, much of it religious, and I find a lot of it hauntingly beautiful.
You ask about my thoughts concerning the Religious Census
. Remember I live in Britain. Our one and only religious census was taken in 1851, more than 160 years ago. I have a copy for the county where I was born (Hampshire), and of course it gives a wealth of information - but probably not about what you're asking about!
