Sir William Robert Seymour Vesey-FitzGerald (1818 – 1885) was a British politician, Member of Parliament for Horsham and Governor of Bombay. He was a son of William Vesey-FitzGerald, 2nd Baron FitzGerald and Vesey. In 1846 he married Maria Tryphena Seymour and was succeeded in 1885 by his eldest son, Sir Gerald Seymour Fitzgerald, who married in 1862 and had three daughters. At the time of Griffith's Valuation Seymour Fitzgerald held land in the parish of Croagh, barony of Connello Lower, county Limerick, most of it leased to Richard C. Smith. In May and July 1857 an estate of about 600 acres belonging to him in the barony of Connello Lower was advertised for sale. In 1862 the 3,000+ acre estate of William Robert Seymour Fitzgerald in the parish of Lismalin, barony of Slievardagh, county Tipperary, was advertised for sale. The estate was held in fee simple and must have been purchased from the Earl of Carrick, the owner at the time of Griffith's Valuation. Three lots were sold to Mr Lysaght (in trust). The remainder comprised of 1647 acres was advertised for sale again in November 1863. However a buyer does not seem to have been found as the Right Honourable Sir William Robert Seymour Vesey Fitzgerald of Holbrook, Horsham, is recorded as owning 1,587 acres in county Tipperary in the 1870s. In May 1875 his fee simple and freehold estates in the barony of Slievardagh were again advertised for sale. These estates amounted to 2,540 acres and included a fee farm rent charged on 959 acres of Mohobber. Five of the eleven lots were sold on this occasion. The Irish Times reported that Messers. Cashan, Fox, Cahill and Barnes were the purchasers. The remainder were advertised for sale again on 3 December 1875. The Irish Times reported that the lots sold on that occasion were bought in trust for Michael Morris at a total cost of £11,200.
