Summary: Is there a (possibly old) print literature/use of the word codecessor?
Background: I intuitively used the word assuming it exists in peer-reviewed publications first around 2008 only to be told recently that codecessor does not exist in English dictionaries. Nobody complained and I was told I was understood when I used word. I then searched myself extensively online to come up with the conclusion that mine was the only predominant use of the word. I've found that strange as I naturally assumed back in the day the word existed and never meant to create a neologism or some such.
Since the word appeared in recent print, I've then gone to Wiktionary and added its definition I meant the word to have. The suggested use of it was either as a noun or an adjective. The Wiktionary entry has been called a protologism since been moved. My definition was:
A (technically) co-descendant notion or concept, but not necessarily a close sibling to concepts alike emerged around the same timeframe from the same or similar predecessor concept(s).
The X is based in part on its Y predecessors and codecessors, such as Z, A, B, and C.
(Other terms I would use would be co-descendant or co-successor, but they didn't end up being used.)
Thus the main question if anyone here has ever come across codecessor elsewhere, such as older print literature, and if yes, what is the reference and a possible definition.
