How many siblings did Princess Diana have?

Princess Diana had four siblings: Sarah, Jane, Charles, and John Spencer.

Diana was the fourth of five children born to John Spencer and Frances Roche. Her older siblings were Lady Sarah McCorquodale and Lady Jane Fellowes, while her younger brother was Charles Spencer, 9th Earl Spencer. Diana also had a younger brother named John, who died shortly after birth in 1960, about a year before Diana was born.

This question can cause confusion because Diana grew up with only three siblings. John’s death meant that Sarah, Jane, Diana, and Charles were the four children who formed the surviving family group. However, when counting her siblings overall, including a sibling who died in infancy, the accepted answer is four.

Diana was born in 1961 at Park House on the Sandringham estate. Her family’s aristocratic background and connections to the royal family later placed her in the public spotlight, but her childhood included the upheaval of her parents’ divorce when she was seven.
