Quins spent a Merry Christmas, 'Santa' Dafoe discovered. Although strictly confined to their Callender (Ontario) nursery, the Dionne quintuplets spent a very merry Christmas.

Photo shows, Yvonne and Annette peer inquiringly at Santa Claus, whom they are beginning to suspect is their own Dr Dafoe.. 2 January 1938
