He was the second son of Richard Brownlow (1553–1638) of Belton in Lincolnshire, which manor he purchased, Chief Prothonotary of the Court of Common Pleas, by his wife Katharine Page, a daughter of John Page of Wembley in Middlesex. His elder brother was Sir John Brownlow, 1st Baronet (c.1594-1679) of Belton, who was created a baronet "of Belton" one day before himself.

From 1653 he sat in the Long Parliament for Lincolnshire.
