I am an Austrian Zeiner. I found the roots of (most of) the Zeiners in the environs fo Lienz (Eastern Tirol). The first records are from 1603. Before there are no birthbooks or something similar. I generated a family tree from 1603 up to now, but there are many dead ends, as persons left from Austria some where else. Perhaps you know a name of one of your ancestors who went migrated from Austria to Germany.
