Ialready posted everything about George Wm Teater already. that land was Bakers Creek which George Teater moved to from Crab Creek. he didnt aquire it in 1783 he sold it 1783 to potterifeld. he aquired the back deed going back to 1777. he only left his family there while he an oldest son went on into Kentucky 1779.
Anyway i think youR line is now narrowed down to Phillip Teeter and Issac Teeter of Washington co MD judgeing from the 1783 tax list Phillip lived near to were Jacob lived in 1790. so we try fir the naming patterns now an search the Wash MD files for thes 2 should produce something beneficial.
