Where do the sister of the great grandfather and the brother of the great grandmother fall into the tree? Are they also direct ancestors of your cousins or simply great aunts and uncles? If the latter, it would have no incidence on the family.

Your best bet is to do some triangulation. Put all your close matches on a sheet of paper and draw lines connecting them. On those lines, write the amount of shared DNA between each pair as well as which segments are shared (different sites have different comparison features).

At the same time, make a tree of all the information you know about those cousins and their ancestry. Cross-reference the two and you should be able to identify which segment came from which ancestor and hopefully find where your place is in that tree.
