A Gloucestershire gentleman ‘of great landed property’ who inherited Barrington Park on his father’s death in 1815, Greenaway styled himself as an ‘independent Whig’.
Greenaway is not known to have made any speeches in Parliament, and other than the 1838 inquiry on the Kinsale election, does not appear to have served on any select committees.
Although Greenaway was undecided on the merits of the Whigs’ proposed fixed duty on corn, having long opposed the anti-corn law motions proposed by Charles Villiers, he offered Melbourne’s administration his hearty endorsement at the 1841 general election.
Re-elected without opposition, Greenaway continued to oppose a free trade in corn, but voted in favour of Peel’s reduction of sugar duties, 3 June 1842. He was part of the majority that resisted paternalist attempts to weaken the powers and authority of the poor law commission, by, for example, curtailing their term and abolishing assistant commissioners, 27 June, 12 July 1842. Greenaway retired shortly after opposing the introduction of the Maynooth college bill, 3 Apr. 1845, citing ‘circumstances of a private nature rendering the longer occupation of a seat in Parliament particularly inconvenient’.
