If you are having trouble reading a document with German town names on it, please send a email scan to me, or post it as an attachment to this message board. It looks like you are just taking wild guesses that will get you nowhere fast.
Here is a Gazetteer for all old Mecklenburg towns at:http://progenealogists.com/germany/mecklen/meckgaz.htm
Gr. Vorschow did not exist, it is mostly likely Gr. Varchow, seehttp://progenealogists.com/germany/mecklen/meckfg.htm
Gr.=Gross in German, and is a reference to Large. Sometimes you will also see a Kl. in front of a town, that is = Klein, meaning small.
For example one of my towns is Gross Belitz and Klein Belitz, which equals the main or large town of Belitz, and the other the smaller one.
