- Ralph Smith of Ballingarry, county Tipperary, was descended from a family of that name originally based in Durham in the north of England. He settled in county Tipperary in the 17th century. His descendants married members of the Jackson, Cornwall, Cooke and Drought families. Ralph Smith of Lismacrory and Milford married Elizabeth Stoney of Greyfort and died in 1814. Their son Ralph Smith married Elizabeth Firman of Firmount and died in 1835 when he was succeeded by his son Ralph Smith Smith, who married Rebecca Bunbury of Lisbryan. At the time of Griffith's Valuation Ralph Smith held an estate in the parishes of Aglishcloghane, Dorrha and Lorrha, barony of Lower Ormond and William Sydney Smith held land in the parishes of Templebeg and Upperchurch, barony of Kilnamanagh Upper. In July 1852 over 800 acres, the estate of Ralph Smith Smith in county Tipperary was advertised for sale. In March 1857 the estate of Ralph S. Smith's son Richard Flood Smith, a minor, including Milford House and demesne, was advertised for sale. In November 1880 the estate of Henry Ellis Smith at Ballymona, 298 acres in the barony of Lower Ormond was advertised for sale. The Smiths of Gurteen and Mount Butler were branches of this family.
- John Sidney Smith was the manager of the Tipperary Joint Stock Bank, Roscrea, until he resigned in 1850 as he had been appointed agent to the 3rd Marquess of Sligo's estate at Westport, county Mayo (''Ballina Chronicle'', 24 July 1850). It is not clear if this Smith family was related to the Smiths of Milford and Gurteen, county Tipperary. Ralph Smith Smith had a son William Sidney Smith but he was too young to be the father of John S. Smith. John S. Smith lived in houses owned by the Birch family in the mid 1840s and was related to the Birches. In the 1870s John S. Smith owned 191 acres in county Tipperary. He died in 1886. His son John Edward Smith lived at Derryvale in the late 19th century. This family may be related to Christopher Smith, a merchant in Roscrea, who died in 1818 as a copy of his will is to be found among papers in the National Archives relating to the Derryvale family. Christopher had sons Samuel, Thomas, Joseph (of Mount Butler) and William.
Smith (Mount Butler)
- Captain Joseph Smith lived at Mount Butler, parish of Corbally, King's County (Offaly). He was the third son of Christopher Smith of the town of Roscrea, merchant, who died in 1818. He appears to have been left most of his father's property and was his executor. His father's will gives details about the acquisition of his property. Samuel Smith of Lisduff is also mentioned in the will. Mount Butler was situated just over the county border with county Tipperary and was very close to the town of Roscrea. In 1823 Joseph Smith married Lady Carden (nee Kemmis), widow of Sir Arthur Carden. He died in 1842. The estate of Joseph Smith of Roscrea at Drumnascart in the barony of Lower Ormond, at Gortnarry in the barony of Kilnamanagh Upper, county Tipperary and at Ballyshane, barony of Ballybritt, King's County (Offaly) was advertised for sale in June 1851. George and Richard Atkinson were purchasers at this sale. Premises in the town of Roscrea, the estate of Joseph George Smith, were advertised for sale in November 1859. The Freeman's Journal reported that they were purchased by Mr. Foy. Deeds in the Baker, Ringwood and Gordon solicitors' collection in the National Archives trace the title of Drumnascart from George Woodman to George Jackson in 1707 to Ralph Smith of Lismacrory in 1748 and possibly suggest a family relationship between the Smiths of Milford and Captain Joseph Smith.
