February 7, 1923
Princess Mary, Viscountess Lascelles, gave birth to a son tonight, reports the New York Times.
The baby was born in London. Queen Mary visited her daughter this morning, and planned to return to Buckingham Palace, but it soon became apparent that that the Princess was about to give birth to her child.
This is the first grandchild for King George V and Queen Mary. Princess Mary married Viscount Lascelles, heir to the Harewood earldom, in February 1922.
The unnamed baby is sixth in line to the throne behind the Prince of Wales, the Duke of York, Prince Henry, Prince George and Princess Mary.
He will be styled as the Honourable Christian name Lascelles.
None of Mary's brothers are married, although the Duke of York will wed Lady Elizabeth Bowes-Lyon in April.
