Originally from Sussex, Bowyer’s father, a younger son, made his fortune as a successful London merchant.
Bowyer’s wife was the sister-in-law of (Sir) Henry Maynard†, a client of Sir Robert Cecil†, and it may have been via this connection that in 1602 Bowyer obtained a lucrative post in the Exchequer; he later acknowledged his gratitude to Cecil, declaring that ‘I have ever depended upon his honourable house’.
During the recess Bowyer was involved in a dispute with the governors of St. Thomas’s hospital in London, concerning a parcel of common land to which he claimed title.
Bowyer does not appear to have stood for Parliament again. His eldest son did not live to take up the reversion to the tellership, dying of smallpox in 1613, but Bowyer himself was still ‘in perfect health’ and ‘owing not one penny to the office’ when he drew up his will on 20 July 1614.
