Napper was licensed in 1626 to travel for three years, but can have been abroad for only a few months, for in November of the following year he was admitted to the Middle Temple. He evidently enjoyed neither experience, leaving instructions in his will that his grandsons should not be educated beyond the seas, ‘and not much in London’.
According to the 1st earl of Shaftesbury (Sir Anthony Ashley Cooper†), Napper was ‘a good housekeeper, well-versed in all his country business’, but otherwise of limited ability, ‘and of a temper inclined to envy ... and to speak as ill as he could of the absent’.
