Not to be confused with his nephew Mark Sittich von Hohenems (1574–1619), Archbishop of Salzburg 1612–19.
Mark Sittich von Hohenems Altemps (1533–1595) was a German Roman Catholic bishop and cardinal.
The addition of Altemps to the family name reflects Alt-Ems (or Alt-Embs) itself deriving from "Alta Embs" (Latin for "altus" = high), like the modern name Hohenems (High Ems in German).
