As per the unfilmed epilogue of "Angels in Manhattan", Amy and Rory adopted a boy, named him Anthony, and Anthony is currently in his mid-60s.
I think some variation of the epilogue needs to be filmed to properly and officially introduce the Anthony character into Who canon. 'Cause I'd like for Anthony to meet the Doctor, and for the two to become friends. Not necessarily have Anthony become a companion or anything. Just... a friend. Establish that, unlike most of his predecessors, this Doctor isn't content to leave his old friends and companions behind, and neglected. He wants to prove to himself that he's a good man? Good men don't neglect their friends, nor those who, like Anthony, allow him at least an indirect connection with old friends.
I'd love to occasionally see Capaldi's Doctor visit with other old friends as well. Not necessarily have them involved with the story, per se, but mostly little more than cameo appearances, to establish that the Doctor no longer runs from his past, nor neglects his past relationships.
