Can you give me Story Help?!?

I've been wanting to write a story on irish/ celtic mythology, ive got a few ideas like an irish bard (famous poet/writer in ireland) who is visited by a banshee (a screaming legend that has foresight to deaths) and is warned that he will soon die. i haven't been able to get a lot of info because of this stupid vampire, and werewolf craze, so do you have any good bits of information of celtic legends that i can use? p.s. im not asking you to give me an idea to write a story, that would make me uncreative and a bad writer, im simply asking for any irish legends you know that i can use in the story
