Why so many of us? Who is the one true Michael Currie?
A name exists to refer to a person — the referential theory of names, which runs back to John Stuart Mill: a proper name denotes an individual and connotes nothing else about them. It follows that the best name is one that refers to a single person, sidestepping the authority-control problem of many people sharing one label. "Michael Currie" falls well short of that, as this wall shows.
You can close the gap by adding detail. "Michael Bruce Currie, born 1982" is probably unique — about 78% likely, given an estimated 500–1,000 Michael Curries, a few percent named Bruce, and one birth year in roughly eighty. Pin down the full date and city of birth and that rises to about 99.9%. A unique identifier removes all doubt:
