"[a-zA-Z][\\s'a-zA-Z-]{0,14}(?<!['-])"

(?<!['-]) is a negative lookbehind assertion that requires that the character which precedes it not match ['-].

Java regex patterns: http://docs.oracle.com/javase/1.4.2/docs/api/java/util/regex/Pattern.html

Perhaps something like this, my regex is not the best and may need to be corrected.

public bool checkStringForHorA(String s){
 s.matches("\\^(-'\\).\\^(-'\\)") ? return true: return false;
}

The regex should check to see if it starts with a - or ', or if after 0 to many characters . it ends with ' or -. If it does then it will return a true, if it does not then it will return a false.
