When, in 1905, G. W. E. Russell commented on converts to Catholicism in the period preceding the zenith of the Oxford Movement, he mentioned six names: three of these were the ‘Cambridge Converts’ Ambrose Phillipps [de Lisle], George Spencer and Kenelm Henry Digby. These permutations,’ he said, ‘were regarded as mere eccentricities, and no one dreamed that they were likely to have any effect upon the Church.’ Did they have any effect on Anglicanism via their point of contact, the Oxford Movement? What were their motives in respect of the Tractarians, and how did they relate to each other as a group? These converts—Spencer and Digby in particular have largely been ignored—illustrate the range of Catholic attitudes to Anglicanism, while Digby represents the main body of Catholic opinion, which was suspicious of Anglo-Catholicism.
