In the 18th century the Joyce family prospered in their mercantile and banking activities and began to acquire land, including the lease of Mervue from the Governors of the Erasmus Smith Schools in 1789. In 1792 they sold property in county Mayo to the Blakes of Towerhill. In the 19th century the Joyces of Mervue held lands in the baronies of Clare (Annaghdown, Claregalway and Lackagh parishes), Tiaquin (Killoscobe parish), Longford and Dunkellin, county Galway and in the townland of Kinlough, parish of Shrule, barony of Kilmaine, county Mayo. By the 1870s they owned 3,742 acres in county Galway, 146 in the town of Galway and 381 acres in county Mayo. Thomas Joyce bought Rahasane Park in 1846 and in 1855 Pierce Joyce was leasing Ardfry House from the trustees of Lord Wallscourt. Frank Joyce was agent to the Earl of Clanricarde between 1882 and 1887. In 1909 Pierce Joyce had accepted an offer from the Congested Districts Board for over 300 acres of his estate.

- Thomas P. Power writes how the Stanleys acquired their Irish estates through the marriage, in 1747, of Lucy, daughter of Hugh Smith, son of Erasmus Smith, to James, Lord Strange, son of the 11th Earl of Derby. James and Lucy's son, Edward, succeeded his grandfather as 12th Earl of Derby in 1776.

At the time of Griffith's Valuation Lord Stanley held two townlands Cooga Upper and Lower, over 800 acres in the parish of Doon, barony of Coonagh, county Limerick. His agent was Thomas Bolton. The National Library of Ireland holds a map of "Coogey", bordered by the townland of Bilbao, dated 1834 but the name of the proprietor is not recorded. This property was bought by Valentine O'Brien O'Connor in the second half of the 19th century  as a report on the provisions of his will published in the ''New Zealand Tablet'' (7 Huitanguru [Sept]1874) states that an annuity of £5,000 was charged on the estate he bought from the Earl of Derby. In the mid 19th century Lord Stanley's county Tipperary estate was in the parishes of Railstown, St Johnbaptist and St Patricksrock, barony of Middlethird and Emly, Kilfeakle, Shronell and Tipperary but mainly in the parish of Solloghodmore, all in the barony of Clanwilliam.
- John Smith-Barry of Marbury Hall, Cheshire and Fota Island, county Cork, was a son of James Hugh Smith-Barry, a grandson of the 4th Earl of Barrymore. Through his grandmother, Lucy Smith, granddaughter of Erasmus Smith, the Barrys had inherited a large estate in county Tipperary. Thomas P. Power writes that in 1755 it amounted to 6,108 acres in the baronies of Clanwilliam and Middlethird. In 1814 John Smith Barry married a daughter of Robert Courtenay of Ballyedmond, county Cork and their fourth son inherited that estate.

The title became extinct and his estates passed to his nephew, Colonel Robert R. Smith-Barry, who passed Fota Island over to the Baron's daugher, the Honourable Dorothy Elizabeth, Mrs Bell. Mrs Bell's daughter, Rosemary Elizabeth Villiers, succeeded to Fota House in the 1970s. In the 1850s James H.
