Jim Wile this is a Mennonite family, and there seems to be a claim linking her to German nobility. Would you mind taking a look?
I believe going through Isacks Hermans Op den Graeff

The speculation is that Gertrude's mother is Margarita Op Den Graeff. That assumes she is the daughter of Reiner Tyson (actually Theissen) . It also assume his wife Margarita had that surname. However, they had nine children including two daughters named in the will Sarah and Elizabeth. No Gertrude.
