In ancient Egypt it was acceptable for royalty to marry within the family, probably in order to help preserve dynastic succession.  King Tut's predecessor Akhenaten and his queen, Nefertiti, had at least six children, but presumably no sons, as only girls are pictured in sculptures and reliefs of the family.  This lack of boys in the main royal line (Akhenaten may have had a son or two, but by other, secondary, wives) made the question of dynastic succession a pressing problem.  As a result it is believed that King Tut married his half sister Ankhesenpaaten, she later changed her name to Ankhesenamen, which means "She who lives through the Amun."  Ankhesenamen was thirteen years old when she became the wife of Tutankhamun when he was only nine years old. The teenage queen apparently suffered two failed pregnancies: the miscarriage of a 5-month-old female fetus and a stillborn baby girl. (Both were mummified and buried in Tutankhamun’s tomb.)

In this papyrus scene starting from the left we see Ankhesenamen offering gifts to King Tut, she holds the lotus flower in her right hand.  The center scene shows a mutual exchange around the lotus and finally we see  the young Queen anointing Tut under the blessing of the Aten (sun).
