Meaning of "Keagen"

I've been asked more times than I can count where my name comes from. I usually tell people I pulled it out of the air. . . . but that's not entirely the truth. It's the meaning BEHIND the name that I like, and that suits me. It's got an Irish/Gaelic root, and the actual Gaelic meaning is "small flame; ardent". I've got a definite spark, and am I EVER enthusiastic. Ardent also carries the meaning of "passionate". Do you guys think it fits? :-D
