Sadly I dont know the owner of the adress. I wanted to buy sth and I got the wrong adress. I think it was the adress the new bitcoin would be sent to if I would have bought some instead of giving my own. Now I have just payed 100€ for free. At least I learned sth from this.
if you don't exactly know who owns the address, can you at least remember where you get the address?
if you copied from a web/exchange site, you should contact the person in charge of that site
wherever you got it from can give you a pointer to who owns that given address (or how to access it)
also just like others said, post the address... so we can start with something and try to figure it out
