Following family custom, Sotherton became a freeman of Norwich as a mercer in 1570; in the same year he was admitted to the London Merchant Taylors’ Company by redemption, joining his brother John and cousin George. He served the Company well until his death, when he—like George—bequeathed it his great gilt standing cup with his arms on the cover, and £25 besides for ‘a recreation’ in the hall. But whereas George was in business as a London merchant, Nowell was ‘bred up’ in the Exchequer with his brother John (who became one of its barons in 1579) and he remained an Exchequer official all his life.
Glimpses of Sotherto’s activities occur in the printed sources for 1594 and onwards,
On the death of his aged brother John, and in spite of the efforts of Julius and Thomas Caesar, Nowell Sotherton was appointed to succeed him in the Exchequer (though only as baron cursitor), the lord treasurer, Thomas Sackville, Earl of Dorset, taking particular pains to ensure that the appointment was made.
