Signage at the location is: Harmony Circle for the park in the middle of the roundabout, no "Lee Circle" on any street signs but there is a sign with a map that calls it "Lee Circle". As the note suggests, "Tivoli Circle" might just be a colloquial version, so I'm leaving that up to local community to decide if that warrants the addition of an alt_name.
