Who wrote the earlier, less detailed Marathi works about saints mentioned in the preface?

The preface discussed in chapter 0 identifies the poet Shri Dasganu Maharaj as the author of three earlier Marathi works: Shri Bhaktalilamrut and Shri Bhaktisaramrut. While these works contain biographies of saints, the text notes that they are not comprehensive or detailed enough for a devotee to perform a Parayan or Saptah of a single saint's life, as these biographies often span only two or three pages within the larger works.
