I have Habicht's book "Niederlinxweiler---Die Familien" (the entire book) as a Adobe .pdf file. This book has been quite useful, but is limited to families in Niederlinxweiler.
What I do not have, & desparately need, is a source for books on families in Oberlinxweiler, Ottweiler & Remmesweiler, or for families in other places in Saarland, & in some cases for families in Bayern & Baden-Wuertemmberg. Other than Drehmer families, I'm especially interested the Schwingel, Wolfanger, Voltz, & Vogel families in Germany with members that emigrated to America, Canada, & Brazil.
One point of information that still eludes me is the meaning of 'Drehmer'. The oldest spelling that I have found in Germany, appear to be 'Drämer' & 'Drähmer' (in Adelsberg), but I believe that the surname is also found elsewhere in Germany as 'Trähmer' & 'Trämer'.
I'm hoping to locate living Drehmers in Germany to correspond with. Unfortunately I am unfamiliar with the German language, so I cannot read or write German, although I do use a good German dictionary to figure out genealogical data.
I have also found Klaus Dufner's web site to be be quite useful.
I would be indebted to you if you can send me your Voltz information.
