GTT. The initials GTT (“Gone to Texas”) came into use in the first half of the nineteenth century, when Texas had the reputation for producing and harboring outlaws. The letters were often chalked on the doors of houses in the Southern states to tell where the occupants had gone. Eventually “gone to Texas” came to be a synonym for “at outs with the law.” Frederick Law Olmsted, in his Journey Through Texas (1857), says that residents of other states appended the initials to the name of every rascal who skipped out, and that in Texas many newcomers were suspected of having left home for some “discreditable reason.”
If you have an ancestor who suddenly disappears from all records, you may want to consider checking to see if he has Gone to Texas.
