Browne must be distinguished from a namesake, his Roman Catholic cousin who was granted an Irish baronetcy in 1622. Browne’s grandfather, Sir Valentine Browne†, was victualler of Berwick, which he represented in two Elizabethan Parliaments. The family had settled at Croft by 1560, when they received a grant of arms.
Following the death in 1596 of his brother-in-law, Edward Tyrrell, warden of the Fleet prison, Browne tried to claim the wardenship for his nephew, Robert Tyrrell, a minor whose wardship had been purchased by Robert Bacon*.
In June 1606, shortly after succeeding to a heavily encumbered estate, Browne obtained a special pardon, presumably through the influence at Court of his uncle Sir Thomas Monson*.
With the help of his extended family an opening was created for Browne when one of the knights of the shire, Thomas, Lord Clinton* was summoned to the Upper House in February 1610. However, Browne’s entry into the Commons was delayed by Clinton’s refusal to leave. A by-election eventually took place in early April, but Clinton alleged that it was held without due notice and sparsely attended, casting the validity of Browne’s return into doubt. The case was referred to the privileges committee, who ruled that Browne could take his seat after Clinton’s departure on 2 June.
Some time after the dissolution of Parliament, Browne seems to have been imprisoned, presumably for debt, since in January 1612 he was released on a writ of habeas corpus.
