Dave,
I also appreciate your taking the time to share these, which will surely prove valuable for continued research related to the 12th Deutsch Banater Grenz regiment.
I encourage everyone on the list be familiar with this data and Dave's previously published research that David Preston noted. In addition to searching for direct surname matches, there are other clues in the data (e.g. transfer locations), and the historical details are very interesting. Also, given the significant internal migration from the Banat's military border to villages further north, source data of this regiment may someday be the key to breaking through other brick walls...
