Hi, I have recently received some information on my Volzer line and, so, I am pursuing many avenues, so to speak. My gGF, Emanuel Gottlieb Volzer (b. May 31, 1835) was born in Wurtemburg, Germany.His father, Johann Georg Volzer(b. May 01, 1807) married Magdelen Rose Roos (b. March 27, 1806).Magdelena's parents are listed as George Michael Roos and Christine RAPP.Based on an approximate age of 20 to 25 years for a generation, this would put Christine Rapp being born about 1780 to 1786. If anyone has any information concerning the RAPP line which might connect to my Christine RAPP, I would appreciate hearing from you.
