Most of Robbins's books appear to have been published anonymously, as by "The Author of 'Win and Wear'"
Cary Sternick's Bibliography of 19th-Century Series Books shows these volumes were reissued in 1892 as part of the Dale and Hillside Series with four additional titles by Robbins: Faith Thurston's Work, Hester Trueworthy's Royalty, Mabel's Stepmother, Robert Graham's Promise. Series order is alphabetical by title, and the works may be unrelated.
Cary Sternick's Bibliography of 19th-Century Series Books with Price Guide also attributes one pseudonymous series to Robbins, though no independent verification of this pseudonym or the titles has been possible.
