Двойническое

Оказывается, у сэра Уинстона Черчилля был довольно известный тезка и однофамилец, тоже писатель:

It was the American Churchill who became famous earlier, and in the 1890s he was much better known than his British counterpart.
The British Churchill, upon becoming aware of the American Churchill's books, wrote to him suggesting that he, the British Churchill, would sign his own works "Winston Spencer Churchill", using his full surname, "Spencer-Churchill", to differentiate the books of the two authors.
