Lambert, whose family originated in Yorkshire, was the great-grandson of Walter Lambert, who in 1726 acquired the lease of Creg Clare, which passed to his eldest son Charles, and in 1729 purchased Aggard, the residence of his second son John and his descendants; his third (Peter) and fourth (Thomas) sons founded the Castle Ellen and Castle Lambert branches of this county Galway gentry family.
In the summer of 1824 Lambert was considered a potential candidate for county Galway or the town, particularly as the nominee of Lord Clanricarde, with whose family he was connected through his father’s first wife. Doubts arose about his attitude to Catholic relief, but in early October he wrote to a local newspaper to insist that he supported it and had signed many favourable petitions.
Lambert, who hardly spoke in the House except to bring up petitions, sided with the Canning ministry against the disfranchisement of Penryn, 28 May, and for the grant for water communications in Canada, 12 June 1827. He attended the meeting of the Catholics of county Galway, 19 Aug. 1827, and voted for repeal of the Test Acts, 26 Feb., and Catholic relief, 12 May 1828. He paired for Fyler’s motion to repeal the Act prohibiting the use of ribbons at elections, 20 Mar. He voted against the Wellington administration for various economies, 20 June, 4, 7 July, and inquiry into the Irish church, 24 June, and against the additional churches bill, 30 June, and the corporate funds bill, 10 July. He approved the formation of a liberal club in Galway town that autumn, when he signed the Irish Protestants’ declaration in favour of Catholic claims.
Lambert chaired the Galway independents’ meeting for extending the franchise of the town to Catholics, 30 Aug. 1829, and spoke for this in the House, 4 Mar. 1830.
Lambert voted for O’Connell’s motion to repeal the Irish Subletting Act, 11 Nov., and Parnell’s for reducing the duty on wheat imported to the West Indies, 12 Nov., and he commented on the Galway town election petition, 6 Dec. 1830. Having been listed by ministers among their ‘foes’, he divided in the majority against them on the civil list, 15 Nov. 1830. He signed requisitions for (but did not attend) county Galway reform meetings in January and April 1831.
Lambert, of whom one radical publication noted that he ‘votes well’, left the House before the division on the second reading of the revised bill, 17 Dec. 1831.
Pleading ill health brought on by his laborious parliamentary duties, Lambert, who married the heiress of a recently deceased Scottish peer that autumn, retired at the dissolution in 1832.
