Help me with a word... Deaner? or Deener?

I hope I'm not wasting bandwidth... but I'm struggling with a word that is driving me insane.
I'm sure I've heard or seen this word before... but for the life of me I cannot find it in any of today's' dictionaries.
The word sounds like "deaner" or "deener" (but I guess could also be spelled diener)... where I THOUGHT I heard it used once as a name for someone who worked as church sexton or verger or morgue or graveyard attendant. I cannot find this word defined anywhere, yet I am sure it is a word.
Please help before I go crazy… If this really is a name for church custodian or a morgue worker (or anything remotely similar) please contact me and provide some info. If not… I guess it's just some nonsense that I made up!

“Deaner” is indeed a word and it is an assistant to one conducting an autopsy. “Deaner” (usu. spelt “deener”) is also Australian slang for a shilling.
According to "Police Procedure & Investigation: A Guide for Writers" by Lee Lofland, a "diener" is an autopsy technician and means "servant."
