1751 Family of Frederick, Prince of Wales by George Knapton (Royal Collection)
From Wikimedia. The Royal Collection has this note for the portrait: "This painting shows the family of Frederick, Prince of Wales. It looks like a normal family portrait – you can see Frederick’s wife, Augusta, seated in the middle of the painting. The couple’s children surround her and are shown playing with toys or enjoying their hobbies.
But where is Frederick? He is not shown in this central family group.
Instead, Frederick can be seen in the portrait at the back left of the painting. Frederick is represented in this way because he died before the picture was painted. Although he is not a part of the central group, it is clear that it is Frederick’s family we can see, from the way he is gesturing with his left hand.
Look closely at the portrait – how many boys and how many girls can you see?
This is a trick question because the small child in the red dress, on the right of the picture, looks like a girl, but is actually a boy – Prince Frederick William – wearing a type of dress for boys, called 'coats.'"
This note makes clear who is wearing the black veil. The Lady to her left is Princess Augusta of Wales, her daughter. The boys wearing Garter sashes are Edward, in red, and George William Frederick, George III, in blue. The infant is Princess Caroline Mathilda, later Queen of Denmark. The two girls in the back row are Princess Elizabeth, with lute, and Louisa, in pink. Princes Henry (l.), William (c.), and Frederick (r.) are in the front row.
