[1] With Hannah Clark, Margaret Cross moved first of all to Overstrand in Norfolk as teacher of music and mathematics, then in 1899 to Coombe Hill House, East Grinstead in Sussex, where apparently, her father, now retired from farming, lived as a border.
[2] In 1909 the Priory in Kings Langley, London was acquired, with Margaret Cross listed as co-principal and responsible for much of the development work.
Then Margaret Cross was invited by Prof Millicent Mackenzie to join her with a group of other teachers from Britain, in attending a course of lectures on education by Rudolf Steiner in Dornach, Switzerland in December 1921.
It was this visit that prompted the two women to offer their school as the first to implement the ideas of Steiner’s education in Britain, a conversion that was to take place over many years.
Shortly after the Stratford lectures, Margaret Cross attended Rudolf Steiner's conference on Waldorf educational practices at Oxford in August 1922.
