on 21 August 1930 at Glamis Castle in Scotland, her mother's ancestral home, and was affectionately known as Margot within the royal family. She was the first member of the royal family in direct line of succession to be born in Scotland since the 1600s. She was delivered by Sir Henry Simson, the royal obstetrician. The Home Secretary, J. R. Clynes, was present to verify the birth. The registration of her birth was delayed for several days to avoid her being numbered thirteen in the parish register. Margaret was baptised in the private chapel of Buckingham Palace on 30 October 1930 by Cosmo Lang, the Archbishop of Canterbury. At the time of her birth, Margaret was fourth in the line of succession to the British throne. Her father was the Duke of York (later King George VI), the second son of King George V and Queen Mary. Her mother was the Duchess of York (later Queen Elizabeth The Queen Mother), the youngest daughter of the 14th Earl and the Countess of Strathmore and Kinghorne. The Duchess of York originally wanted to name her second daughter Ann Margaret, as she explained to Queen Mary in a letter: "I am very anxious to call her Ann Margaret, as I think Ann of York sounds pretty, & Elizabeth and Ann go so well together." King George V disliked the name Ann but approved of the alternative, Margaret Rose. Margaret's early life was spent primarily at the Yorks' residences at 145 Piccadilly (their town house in London) and Royal Lodge in Windsor. The Yorks were perceived by the public as an ideal family: father, mother and children, but unfounded rumours that Margaret was deaf and mute were not completely dispelled until her first main public appearance at her uncle Prince George's wedding in 1934. Margaret was educated alongside her sister, Elizabeth, by their Scottish governess, Marion Crawford. Margaret's education was mainly supervised by her mother, who in the words of Randolph Churchill "never aimed at bringing her daughters up to be more than nicely behaved young ladies". When Queen Mary insisted upon the importance of education, the Duchess of York commented, "I don't know what she meant. After all I and my sisters only had governesses and we all married well — one of us very well". Margaret was resentful about her limited education, especially in later years, and aimed criticism at her mother.
