Usualy early west Slavs were called Venedi in latin sources. South germans called Slovenes and Serbo-croatians Windisch. North germans called Sorbs, Czech, Slovaks and Poles Wenden. Maybe there is conection.
I was not talking about specific Veneti from specific region, but Veneti as whole. Sometimes I like to speculate on the origin of the Slavs, based on linguistic similarities, geographical names, legend and song lyrics. From this I can draw a lot more interesting conclusions than analyzing scientific theories. As for Veneti, I found this interesting video about the origin of the Slavs, which I posted on the forum for the further potential discussion.
