It does not take much to imagine the emotions of the two de la Mare sisters, then in their mid-eighties. The idea of a memorial in Holy Trinity Church was received with enthusiasm as a most fitting way to mark not only the school’s closure but its long connection with that church, where the girls had attended services and been confirmed. The Vicar, the Rev A L Evan Hopkins, welcomed the proposal, explaining that the church still needed two replacement stained glass windows for the north aisle, and offered one as the site for the memorial.
Mr Frederick Cole of Nonnington, a stained glass artist whose works are known in many countries, was asked to submit a design, and the de la Mares started collecting donations from their Old Girls. As it was an expensive project, contributions were also invited from Mrs Kathleen Whiteside and the Old Girls from the Hasson era, to which they readily agreed.
The inscription reads:
To commemorate
the close association
of this Church with
Saint Margaret’s School
from its foundation
1890 1967
In the left panel stands St Margaret and in the right is illustrated the double front facade of the main school building, 35-37 Earls Avenue. Above these are six famous women: Elizabeth Fry, Mary Slessor, Florence Nightingale, Edith Cavell, Mother Teresa and Gladys Aylward.
The orange shape beneath the picture of the school building is the heraldic 'maunch' or 'sleeve' from the the de la Mare coat of arms.
Mr Cole exhibited a cartoon of the design to a gathering in the home of Johanna Lack in September 1968. The funds were raised to cover the cost, approximately £600, the window made and installed, and dedicated at a service of thanksgiving on Saturday 24 May 1969 by the Dean of Canterbury, the Very Rev. I.H. White-Thomson, husband of Wendy Woolliams. Afterwards a tea party was held in the church hall at which Miss Marguerite de la Mare and Mrs Kathleen Whiteside cut a cake decorated with white icing and a blue inscription "St Margaret’s". A great effort was made to keep the mood of both the service and the tea party a positive and cheerful one.
