Why is it usually “friend of his”, but no possessive apostrophe with “friend of Peter”?

I'm currently having hot debates with a friend of mine about which one is more natural and more grammatically correct:

  • A friend of Susan
  • A friend of Susan's

I vote for the first, but I don't have anything to prove I'm right.

    I disagree that this is a duplicate; the other question is about pronoun usage, this is about whether you add apostrophe-s to a name. – Tom Hughes Aug 01 '17 at 23:56

A friend of Susan’s is a double genitive, which has been a feature of English grammar for centuries, and it is the normal alternative to one of Susan’s friends. Just as most people would say a friend of mine, rather than a friend of me, so a friend of Susan’s, rather than a friend of Susan, would be the natural choice in most contexts.
