Alexander Norwich Tayler (11 July 1870 – 8 November 1937) and his sister Helen Agnes Henrietta Tayler (24 March 1869 – 10 April 1951) were British historical writers, specialising in 17th and 18th century Scottish and English history.
Helen Agnes Henrietta Tayler, known as Hetty Tayler was born in London. Her brother Alexander, known as Alasdair Tayler was born 16 months later at the family summer home in Rothiemay, Banffshire, Scotland. Their parents, William James Tayler and Georgina Lucy Duff, were descended from noble multi-generational Scottish and English families, whose long aristocratic histories provided much material for the two future historians in their formative years.
