Maher was born in Cashel, the son of a local Catholic physician, and early in life assumed the management of some of the largest estates in the counties of Limerick, Clare and Tipperary. On inheriting the Turtulla estate of his cousin, Valentine Maher, he became a resident proprietor in Tipperary, where he was well-regarded as a landlord.
A life-long admirer of Daniel O’Connell, Maher was selected by the independent electors of Tipperary in January 1844, to fill the vacancy caused by the death his cousin, Valentine Maher. His fervent support for repeal meant that he did not, therefore, receive the approval of the local Catholic gentry, but he secured influential backing from Charles Bianconi, the stage coach operator and former mayor of Clonmel.
In the Commons, Maher supported Lord John Russell’s motion for a committee to consider the state of Ireland, 23 Feb. 1844, but, convinced that ‘an Irish member of parliament can’t do the shadow of service to Ireland’ at Westminster, where his opinions were ‘treated if not with contempt, at least with total disregard’, his contributions to debate were rare.
He was, however, active in local politics, and despite rumours that he was to retire, he was returned again as a repealer for Tipperary in 1847. At the hustings he expressed a preference for the return of Sir Robert Peel to the premiership and, in seeking to protect the legitimate rights of resident Irish landlords, advocated an absentee tax on those residing outside the country.
Early in 1850 Maher refused to comply with an address from a delegation of Tipperary landholders ‘to advocate protection or resign’, but did advocate a revision of the poor laws that might alleviate the financial burden on landowners.
Thereafter Maher remained an active and influential figure in the ‘independent’ politics of county Tipperary.
Having been forced by failing health to retire from public life, he died at his residence in October 1871, and was buried at St. Mary’s churchyard, Thurles. He was remembered as one of Ireland’s ‘most fearless champions … always to be found in the front, fighting the good old cause’.
