Hi, my names Austin Floyd, and my mom's maiden name is Trullinger. Jacob was the son of Adam, one of 11 children. My ancestor, was Gabriel, one of the 11. We can date back the Drollingers to Melchoir Drollinger, born 1572 in Dietlingen, Karlsruhe, Baden, Germany. He he had a son, Wendolin, born 1616 in Ellmendingen Baden. Wendolin, with Margaretha Drollinger, had a son, Michael, born in 1654, also born in Ellmendingen Baden, Germany. Michael, with Maria Funck, had Hans Micheal, born 1677. Hans Michael, with Eva Klemmer (or Clemmer) had the 11 children that we are descendants from. I hope that was of use.
