Faith of Samogitia: what's known?

The last Pagan stronghold of Europe, Samogitia was christened as a consequence of Northern Crusades - and that came more than a thousand years after Theodosius. It's marvelous, actually, that there were Pagan lands in Europe at the beginning of Renaissance.
But. What we actually know about Samogitian faith? It's definitely not that classy among scholars and amateurs like Graeco-Roman polytheism or Old Norse religion...
... but do we know at least something?

I guess there is much stuff known, simply because there is neopagan movement in Lithuanian called Romuva, I guess there are some for Samogitians as well

Here is some link about I found after few minutes, it's more about Lithuania but maybe some literature may direct you further into Samogitia specifically
