In his will Ommanney’s father, who rose to the rank of rear-admiral, recorded his gratitude to his brother Edward, of Bloomsbury Square, ‘for the assistance he has given me to establish my children in life.’
Ommanney may have been descended from Huguenot immigrants who had settled in Devon and his father owned a house at Plymouth,
Ommanney joined the handful of assorted radicals and independents who divided against the Westminster hustings bill, 3 Feb., but he voted with government on the complaint against Wyndham Quin, 29 Mar., Tierney’s censure motion, 18 May, and the foreign enlistment bill, 10 June 1819. He voted against the extension of the franchise at Penryn, 22 June. He had spoken against the chimney sweepers regulation bill, 12, 17 and 22 Feb., arguing that the existing laws afforded sufficient protection to the ‘gay, cheerful and contented’ climbing boys, whose replacement by machinery of dubious efficiency would increase the burden on the poor rates. He probably supported most aspects of the repressive legislation of late 1819, but he bridled at the provision made for night searches in the seizure of arms bill: he voted against the offending clause, 14 Dec., and declared his intention of voting against the entire measure because of its retention, 15 Dec., though his name does not appear among the minority who subsequently voted for Lambton’s wrecking amendment. He was in the majority in favour of the banishment clause of the blasphemous libels bill, 23 Dec.
Ommanney, whose naval agency was carried on after his death by one or more of his sons, died 7 Nov. 1840, ‘aged 66’.
