Name notes

Leigh is a middle name, not a separate stage surname. Prefer Britannica/LOC fuller form Gillian Leigh Anderson when sites omit the middle name. She has used both American and British residency/accents publicly; that does not change the documented birth name or Chicago birthplace.

Transatlantic stage and television work after The X-Files cemented Gillian Leigh Anderson as more than a single-role star; Britannica and LOC remain the preferred citations for the Chicago birth date and fuller name.

Publishing under her own name and high-profile stage roles in London reinforce that Gillian Leigh Anderson is a working identity far beyond 1990s sci-fi fandom.

Emmy and Golden Globe recognition for Dana Scully established her awards profile before later limited-series work extended it.
