Hello Tim,
unfortunately I don't have this two persons in my datas. I think thea came from Oldenburg but we don't have all datas from all parishes. But you can write to the Offizialat in Vechta under archiv@bmo-vechta.de. They copies of most of the church books of that region. If you got the right datas I would proud to present it on our page!
I have no experience with the region Bielefeld and Gütersloh. But you can try the Westfalen-list about this page westfalen-l - genealogy.net.
Good luck!
Gunter
