But I feel I need some regex function to handle common exceptions, such as: "O'Hara", "McDonald", "van der Sloot", etc It's not so much that I need help constructing a regex statement to handle the three examples above (tho that would be nice), as it is that I don't know what all the common exceptions might be. Surely
