Thus, the trash comes from the name of the eponymous prefect (= who gave him his name). But one cannot write, in good French, that "the prefect Poubelle gave his name to the eponymous utensil" (this formulation implying in fact that it is the utensil which gave his name to the man, then that it is the reverse).
Without animosity ...
Edit / Even though? At the proofreading, I specify.
It would have been necessary to say "homonym" (of the same name).
Now, if you wanted to know if he or a relative who made the patent, "eponymous" is appropriate behind the person.
Last case, very likely, as you wrote:
the member "Grelinette" chose his nickname, because he likes this tool. In this case you are good! it is the tool which to give his name to the person.
(Thanks, that allowed me to know how to use this adjective ...)
