- Thomas Frewen was one of the principal lessors in the parishes of Ballymodan and Inishannon, baronies of East Carbery and Kinalea, county Cork at the time of Griffith's Valuation. His ancestor was a Cromwellian soldier who settled in the Castleconnell locality of county Limerick in the mid 17th century. The Frewen property was formerly the Adderley estate. The Frewen Papers contain a mortgage for £40,000 from John Frewen Turner (father of Thomas) to Edward Hale Adderley in 1830 (FRE/402). The Frewen estate amounted to almost 3,000 acres in the 1870s. Property at Gardenhill, Stradbally, county Limerick, owned by members of the Frewen family, was sold in the Landed Estates Court in March 1862. The purchaser was Mrs. Mary Steven of Limerick. Lands in county Limerick in the ownership of Margaret Frewen were offered for sale in the Land Judges' Court in March 1886. Mrs. Frewen indicated her interest in their purchase and the sale was adjourned.
- Thomas Adderley (1712-1791), son of Francis Adderley of Innishannon, county Cork and Elizabeth Fowkes and descendant of Edward Adderley and his wife Mary Hale of Innishannon and Alderley, Gloucestershire, was a politician and developer of the linen industry. He married firstly the widow of the 3rd Viscount Charlemont and secondly Margaret Bourke of Oory, county Mayo and was related to many of the influential families of the 18th century - Loftus, Gardner, Bernard for example. He held an estate in the Innishannon locality which became heavily encumbered following the succession of his son Edward Hale Adderly (died 1870 aged 100) and was acquired by the Frewens pre Griffith's Valuation. see http://www.innishannonschool.com/history16a.htm
