His younger brother was Sir William Brownlow, 1st Baronet (c. 1595–1666) of Humby, Lincolnshire, who on 27 July 1641, one day after his brother's baronetcy, was also created a baronet, "of Humby in the County of Lincoln", whose great-grandson John Brownlow, 5th Baronet (1690–1754) was in 1718 created Viscount Tyrconnel, in the Peerage of Ireland, whose sister and heiress in her issue Anne Brownlow married Sir Richard Cust, 2nd Baronet and was the mother of Sir John Cust, 3rd Baronet (1718–1770), Speaker of the House of Commons, whose son in 1776 was created Baron Brownlow, the ancestor of Earl Brownlow, of Belton House.
Career.
He inherited the manor of Belton, Lincolnshire which his father had purchased, and was selected High Sheriff of Lincolnshire in 1640 and 1665.
Marriage.
He married Alice Poultney (1606 – 27 June 1676), second daughter and co-heiress of Sir John Poulteney (1585–1617) (or Pulteney) of Misterton in Leicestershire, a Member of Parliament for Wigan in Lancashire in 1601 and 1604, by his wife Margery Fortescue (d.1613), a daughter of Sir John Fortescue (c.1531–1607) of Salden, near Mursley, Buckinghamshire, Chancellor of the Exchequer.
