For the last time, Imrahil isn't the only one that had elven ansestors, a number of noble families do. I'll make a list of these someday. ..

I believe that Tolkien did specify that the only elvf-human marriages were listed (it makes more sense if you just say that it's the royal family but in a very broad manner)
