This branch of the Roche family of county Cork was descended from Edmond, second son of Edward Roche of Trabolgan and his wife, Catherine Lavallin. Edmond, by his wife Barbara Hennessy, had two sons, the eldest, Edmond of Kildinan was grandfather of the 1st Baron Fermoy. In 1796 Edmond's second son, Francis of Rochemount, married Esther Webb and they had two sons, Francis James and John Webb of Rochemount. At the time of Griffith's Valuation John W. Roche held land in the parishes Monanimy, barony of Fermoy, Templeusque, barony of Barrymore, Cloyne, Titeskin and Corkbeg, barony of Imokilly. In July 1853 the estate of John Webb Roche at Ballindinisk and Pouladown, over 800 acres in the barony of Barrymore, was advertised for sale. In April 1856 his estate in the baronies of Fermoy and Imokilly was advertised for sale. This estate amounted to 3265 acres in total. The original lease of Cloughbolly or Nagle's Mountain in the barony of Fermoy was from Hugh Millerd to Francis Roche in 1775. The lands in the barony of Imokilly were held on a lease from Edward Roche to Francis Roche dated 1770. The Freeman's Journal reported that two lots were purchased by Mr. Smith and a third, in trust, by Mr. Kilt. Rochemount itself was again advertised for sale in July 1857.
