No. However, something has lead me to suspect that they may be related to the Xiongnu, nothing specific I can point out though.
Which Picts?
There are two of them that I am aware of. "White" ones, and some from the Mongol region (Xiongnu)
Their connection (and reason for the shared name) could be due to the Aryans of before either. The Picts could be seperatists from the same tribe that went to India all those years ago. One on either side of the caucus mountains.
