I took a moment to realize there’s a place called Gary, Indiana. And that there isn’t just some guy who is so infamous that he’s just known as Gary.
However, Michael Jackson is from there. So there’s that.

There are no coincidences.
And even before Gary Cooper there were people using it for Gerald (spear power), Gerard (spear hard/brave), and (old) Gerbert (spear bright). It is a cousin to, but believed not historically derived from, Garrett/Garrod. It is unclear whether German/Germain derive from this root or not. It is usually unrelated to Jared (which is usually a Hebrew name, but does have spelling variants that overlap Garrod).
