Every genealogical researcher sooner or later runs up against what is known as a "Brick Wall." In other words, an area of research where, despite all efforts, nothing seems to fit and no further progress can apparently be made. In the case of one-name studies, such as my Titus lines, the brick walls have tended to multiply. I am listing some of them here in the hope that visitors to this webpage will be able to solve some of these puzzles.
Each one of them will provide a unique challenge. I believe the key is to keep working on them from all directions. Noli illegitimi non carborundum.
