Question about Moses and the Pharaoh of Egypt?

If the umption that The Pharoah of Egypt at that time was Ramesses II then his daughter's name was Thermuthis. If this umption is not correct then it's very hard to find the name of the Pharaoh and his daughter because if you search in wikipedia a href="http://en.wikipedia.org/wiki/Moses" rel="nofollow"http://en.wikipedia.org/wiki/Moses/a you may notice that there is considerable uncertainty as to what date the Bible implies for the Exodus taking place.
