Mrs. L. Borinevitch may have been related to Valentin Gabriel Borinevitch (alias Bourne), a Signalman in the HKVDC (see https://www.findagrave.com/memorial/168562407/valentine-gabriel-bourne_borinevitch )
Mrs. L Borinevitch was stationed at La Salle Relief Hospital during the Battle of Hong Kong and does not appear to have been interned at Stanley Camp. Her name/signature appears under "La Salle College" (La Salle Relief Hospital) and under the caricature of a nurse on the "Day Joyce Sheet" held by the Imperial War Museum.
See: https://www.iwm.org.uk/collections/item/object/30083388. An explanation of the "Day Joyce Sheet" is given at: https://gwulo.com/media/46458
