Question: is middle name and middle initial the same

Answer: No, In the United States, such names are specifically referred to as middle names; in most other countries, as far as they are given names and not, for example, patronymics, they would simply be regarded as second, third etc. given names. In the U.S., the ``middle name'' is often abbreviated to the middle initial (e.g. Mary Lee Bianchi becomes Mary L. Bianchi, which is usually standard for signatures ) or omitted entirely in everyday use (e.g. just Mary Bianchi). An individual may have more than one middle name, or none. In the United Kingdom, for comparison, she would usually be referred to as either Mary Bianchi, M.L. Bianchi or Mary Lee Bianchi, or she may choose Lee Bianchi, and informally there may be familiar shortenings.
