When was the word "everstill" first used and by whom . . . I made it
up in a poem in 1981 so I was naively surprised when anything turned
up.  It has enormous significance to me  and is the last name of my
pen name.

I don't know which of these is the earliest, but here is a list of
places where everstill can be found. Also I checked up the Oxford
English Dictionary. It doesn't have an entry there.

Everstill's father is a Mr Ersel Lamar Hall, so I'm not sure if she
was born with the name surname Everstill in 1940.

Track 1. Cry The Everstill Dream

Your eyes shall burn the passion cry
As black clouds call the fire's kiss
For the smoke shall dance the sweet muse tears
And lay you down (in sorrow)
As I cry the everstill dream
