Pastor Bernhard Pötker

It would be wonderful if anyone could send information about my ancestor Lutheran Pastor Bernhard Pötker who was born ca. 1597 and maybe at Melle-Buer or Bielefeld. He died 18 June 1663 at Barkhausen-Rabber. He was a scholarship student at Bielefeld Ratsgymnasium, attended the University Brunschweig and graduated from University Helmstadt with a Master of Arts Degree on 24 September 1620. He held these positions:

                                        1630 Rector Bielefeld Ratsgymnasium
                                        1631-1633 Pastor Lutheran Schildesche-Bielefeld
                                        1634-1649 Pastor Bad Iburg and Glane
                                        1650-1633 Pastor Barkhausen-Rabber

            He married at Bielefeld Margereta Hellersieck born 1614 and died sometime after 1633 at Barkhausen-Rabber. Her father was Johann Hellersieck born at Werther and a prominent Bielefeld citz offical. His father ? Hellersieck and grandfather F. Heilersieg were both born at Werther.

            Perhaps Pastor Berhard Pötker was the son of Lutheran Pastor Caspar Pötker who was Pastor at Buer bz Melle from 1589 to his death in 1616.

            Any information would be greatly appreciated!
