My "Suk" family is from the Netherlands, where we trace our roots back to the early seventeenth century, when the Veendam, Groningen area was populated (in part) by refugees from Munster, Germany.
My son did spend all of last year in the Czech Republic, where he was thrilled to discover that Suk was a common and even respected name, given the exploits of the Suk musicians. But no genealogical connection, as far as we can tell.
