The title 'Niranam Grandhavari' was coined by historian Edamaruku Joseph in his book Kerala Samskaram.
[5] There was a legend that an uninterrupted chronicle was kept by the primates (Archdeacons) of Malankara Church until 1653, which Mar Thoma VI might have used as a reference.
In addition to this, the nature of the text indicates that it was written by persons closely associated with Mar Thoma Metrans.
[7][2]: 20, 28 The oldest surviving palm-leaf manuscript (thaliyola) of Niranam Grandhavari comprises 179 palm leaves, with writing on both sides.
[8] In addition to these manuscripts, several hand-written copies of this Chronicle are kept in the possession of multiple families and persons in Kerala.
