I think a middle name is very useful. I actually go by it at work because there is another with the same, uncommon first name. I love my middle name and sign everything with my middle initial. They're also useful for documentation. My mom went to high school with a girl who had the same first and last name. I work in a dictir's office and we have several sets of patients with the same first and last name and the same date of birth, that middle initial is handy!!
