The edge cases in this example are trivial to generate: length 1, or empty string. ("Ends with the letters MR" isn't on this list, and is awfully specific.) If you do nothing but have a text field that can contain anything at all the user chooses to type, that will work!
Add in "user X's name changes to Y on date Z" (hard to put in a list of edge case names) and you've covered 98% of these issues.
