- Smith indicates that the first Sir Edward Denny was granted over 6000 acres in county Kerry after the Desmond Rebellion. Sir Arthur Denny was granted an estate in 1666 following the Acts of Settlement. At the time of Griffith’s Valuation Sir Edward Denny owned several townlands in the parish of Annagh, barony of Corkaguiny, parish of Killorglin, barony of Iveragh and the parishes of Ardfert, Clogherbrien, Ratass and Tralee, barony of Trughanacmy. Collingwood Denny leased several townlands in the portion of Annagh parish in the barony of Trughanacmy. Rev. Robert Denny was the principal lessor in the parish of Killorglin, barony of Magunihy, at the time of Griffith’s Valuation.
In 1864, lands at Ballymacgegoge, barony of Trughanacmy, leased by Richard Jeffcott from the Denny estate, were offered for sale in the Landed Estates Court. The Irish Times reports that they were purchased by Christopher Jeffcott and Mr. Hurley.
In 1867, property in Iveragh barony which had been leased by Rev. Robert Day Denny to Michael Lynch was offered for sale in the Landed Estates Court.
In the 1870s the Denny estate in county Kerry amounted to over 21,000 acres.
A junior branch of this family held land in the parish of Colman, barony of Middlethird, county Tipperary and in counties Fermanagh and Monaghan. Anthony Denny married Sarah Jane daughter of the Reverend G.P. Lockwood and their son was the Reverend Edward Denny (born 1853) of Moorestown, county Tipperary. In the 1870s the trustees of the late Anthony Denny held 1,988 acres in county Tipperary and estates in counties Fermanagh and Monaghan.
- In 1906 Charles Edward Denny held untenanted land at Ballybrada and Cranna in the Clogheen locality of county Tipperary. He was the eldest son of Abraham Denny of Rockfield, county Waterford and later of Ballybrada. Abraham established a bacon business in Waterford and then became an architect. He died in 1892 leaving a fortune of nearly £175,00, see http://www.dia.ie/architects/view/1477
Charles Edward Denny of Ballybrada married Ellen Rose of Malta and had a son Gerald Henry Maynard Denny. The use of the christian name Maynard suggests a link between this family and the Denny family baronets.
