The Brownlow family were among the largest landowners in Armagh and in 1799 possessed a total rent roll of £9,000.
Brownlow is not known to have spoken in debate and does not seem to have been a reliable attender, though he voted with ministers on the Scheldt inquiry, 23 Feb., and, according to a report subsequently contradicted in view of his absence,
Brownlow was still listed a government supporter after the election of 1812. He voted against Catholic relief, 2 Mar. and 24 May 1813. He died 10 July 1815.
