If your aunt Tillie was religious, you might check with the various congregations in Hartford and West Hartford and/or with cemeteries if she might have been buried there. It's important to check West Hartford as well as Hartford because as synagogues moved, they tended to move to West Hartford. East Hartford and other nearby towns are another possibility since all cities are close together (as you may know, CT does not have county government and all cities and towns are contiguous). Good luck!
