Evelina

A London original written in English, so no UK-versus-US and no original-language precedence question arises — the 1778 Lowndes three-volume set is the only true first. The anonymity is part of the identification: the first edition carries no author's name on the title page, Burney having concealed her authorship from Lowndes (the manuscript was delivered by her brother in disguise and copied out in a hand unlike her own). The census note's claim about the sum Burney received is biographical, not a point of issue, and is not an identification test.
