I'm writing a story I haven't picked up since 1995... I have no copyright date on it, but the paper is old and dog-eared. The main character of my story, whose name is extremely important TO what makes the character itself, is the same name as another main character in someone else's book published recently. The name is distinctive enough that I would now seek copyright and likeness trademarks. This character and story is beloved to me and if someone comes along and goes 'hey' it would shred it all apart. What can I do and since this person is published, will it stand? I will not reveal the name. I am kicking myself.
