McTaggart's grandfather, Thomas Flower Ellis, Q.C. [...] married Susan McTaggart, sister of a Scottish baronet, Sir John McTaggart. Sir John had no son; to win his favour Francis Ellis, son of Thomas Flower Ellis, gave his own son the forenames John McTaggart. This ploy [...] proved successful. Sir John left money to Francis Ellis conditionally upon a change of surname from Ellis to Ellis McTaggart. This was the way that at an early age Francis Ellis's son, the future philosopher, became John McTaggart Ellis McTaggart; this remarkable style appears in full on the title-page of every book McTaggart published
