The book I referred to is 'The Dreisbach Book'printed for the Dreisbach Family Association, 1998. You can learn more about the Dreisbach Family Asso. by contacting Carrie Bodensteiner at (firstname.lastname@example.org)she will be able to tell you if any of these books are still available.
As for your Magdalene DREISBACH, she is of the Simon DREISBACH,Sr.(1698-1785)line.
Her father Jacob was born 27 Jul 1759 Northampton Cty, PA. d. 14 Jan 1817, Northampton Co., PA. Married Anna Margaret BIEBER, b. 27 Mar 1763, m. 1783, d. 6 Apr 1857, buried Zion Stone Church, Kreidersville, PA.
Magdalene DRIESBACH married John BOYER, b. 16 Jan 1783, m. bef 1806, d. 24 Sep 1852, buried St. Johns Howertown. They had 10 children and I am guessing you have those names, if not, let me know and I will send them to you. Your dates of birth/death for Magdalene are correct.
Your Jacob was in the third generation and his parents were:
Jost (Yost) DREISBACH, b bef 18 Sep 1721, Oberdorf, Wittigenstein, Germany, Christened 18 Sep 1721, d. 17 Oct 1794, buried Zion Stone Church, Kreidersville, PA. He married Elizabeth RACHENBAGER, b. 17 Mar 1723, m. 17 Oct 1749, d. aft 1799.
The parents of Jost are as follows:
Simon DREISBACH,Sr., b. bef 07 Aug 1698 Oberdorf, Wittgenstein, christened 7 Aug 1698, d. 31 Mar 1785, Northampton Co., PA, buried Kreidersville.

Hope all this helps get you started in the right direction.
