Hello Fr Hawickhorst,
I am also decended from Henrich Sandman & Gretke Krogmann. They resided in Lohne, Oldenburg. I have many ancestors from the Steinfeld/Lohne area.
Henrich and Gretke had a son named Gerhard (abt 1636 - 30 Sep 1717), who married Anna Vortman 9 Feb 1682/83 in Lohne. Would your Otto Vortman and Catherine be her parents?
I also have Dultmeyer, Stuckenborg, Stuve, and Zerhusen in my tree.
B Rgds
