Prince William (William Arthur Philip Louis) (1982-living) of Wales, UK on his mother Diana's lap with his father Charles looking on, photographer unknown in 1983. William is the 1st Child of Diana Frances Spencer (1961-1997) Princess of Wales, UK & Charles (Charles Philip Arthur George) (1948-living) Prince of Wales, UK (m. 1981, div. 1996).
Diana & Charles, no year was given. She looks pretty thin in this pic, so it must be early to mid 80's. Only after she stepped outside that family for friendship and reality checks did she begin to come into her own.
