author
A little-known early 20th-century compiler of parlor entertainment, this author is remembered today for Fun for the Household: A Book of Games, a lively collection preserved by Project Gutenberg.

by Emma J. Gray
Project Gutenberg lists Emma J. Gray as the author of Fun for the Household: A Book of Games. Based on the available records I could confirm here, that book is the main work currently associated with her.
Very little biographical information appears to be readily available from the sources I found, so it is safest to describe her as an obscure or lightly documented author rather than fill in uncertain details. Her surviving reputation rests on a practical, entertaining volume meant for home amusement and social gatherings.
