Mrs. M. E. Bliss-Willson

Can anyone point me to corroborating source material for M. E. Bliss-Wilson (http://hymnary.org/person/Willson_ME)? I can't find a record of her anywhere else on the Internet. The closest I can come is Mary Elizabeth Bliss (1842-1906), at https://www.ancestry.com/genealogy/records/mary-elizabeth-bliss_29051513

I'd like to clear up what seems to be possible misidentification of this author.
