I don't know if there are any Targaryens who don't have silver blonde hair, even if they're not inbred. If it's Jon Snow, he'd be the first AFAIK.

Spoiler!

Firstly I do believe Jon Snow is the son of Ned's sister, but the whole hair color thing got me thinking. Based off the Stark family as an example, the eldest child of each sex will don the hair color of the mother. Catelyn Stark has red hair, and so does Robb and Sansa; if you look at Bran and Arya, they have brown hair. So regarding Jon Snow being a Targaryen and not having blonde hair is because Lyanna is the mother and he is the first/only born child, thus he has brown hair. This is all my own speculation and I only have limited resources to the show because I don't read the books. Maybe someone that has more information from the books can chime in on this.
