Input: Question: Which of William Scarlett's children is the oldest? Passage:In 1863 he married Helen Magruder, daughter of Commodore George Allan Magruder, of the United States Navy. They had one son, James. They had two daughters, Ella Campbell Scarlett who studied medicine at London School of Medicine for Women and the Royal Free Hospital and became the first female doctor in the state of Bloemfontein, South Africa, and Evelina, who married Major Henry Haverfield, was a suffragette and an aid worker during World War I. One of the two main family estates at this time (the other being the house that is today Inverlochy Castle Hotel) was Abinger Hall, at the foot of the North Downs in Abinger, Surrey. The third baron sold it in 1867 to a Mr Gwynne, who soon thereafter sold it to become the family seat of the statistician recently created first Lord Farrer, who rebuilt the house on that land.
