We don't consider a word's etymology to be marginalia, so we'll start off by telling you the etymology of this one. Marginalia is a New Latin word that borrows from the Medieval Latin adjective marginalis ("marginal") and ultimately from the noun  margo, meaning "border." Marginalia is a relatively new word; it dates from the 19th century despite describing something—notes in the margin of a text—that had existed as far back as the 11th century. An older word, apostille (or apostil) once referred to a single annotation made in a margin, but that word is rare today.
