NOT SURE WHAT SYMBOL IT IS

I GOT A TATTOO ABOUT 6 MONTHS AGO AND NOW IM IN DOUBT OF THE SYMBOLS. ITS TWO SYMBOLS FOR SON. BUT WHEN I DID RESEARCH ON IT, ONLY ONE OF THE SYMBOLS THAT I HAVE MATCHED MY RESEARCH. I WAS WONDERING IF YOU CAN HELP ME FIGURE OUT WHAT THE OTHER SYMBOL MEANS. HERES A LINK OF MY TATTOO. http://viewmorepics.myspace.com/index.cfm?fuseaction=viewImage&friendID=28226307&albumID=71318&imageID=6157736

I have no idea, but it sure doesn't look like any kanji I've ever seen.
