it´s nice to meet you here again! Thank you very much for your kind contribution, which is very interesting. I believe, that the name is mispelled in the documents. 1. Vrobose is most likely Froböse 2. It´s certain, that "Dorigsen" is "Dörrigsen", which is a part of Einbeck now.
I am wondering, if that Friederike Froböseis identical with my gggaunt Johanne Justine Friedericke Froböse, born 15/12/1832 in Edemissen, which is a part of Einbeck as well. (same prename, same age, same region). See also http://members.tripod.de/froboesefamily/edemissen.htmlhttp://members.tripod.de/froboesefamily/edemissen.html
P.S.: Do you have new results concerning the Froböse/Nebelsiek-line?
