17. Walter Blake
The names of those granted property in the Williamite Settlement demonstrate vividly how the transfer substantially altered the pattern of landownership. Those granted property in Kinvara include Colonel Carey Dillon, brother of the 3rd Earl of Ormond, under whom he served in the war against Parliament; Peter Skerrett of Akin, another Galway merchant; Sir Thomas Merredith, Col. William Knight, and Col. William Shaw, and William Tuite. Another new owner was William Taylor, a Wiiliamite supporter. The Taylors were to become one of the most prominent families in south Galway; their estate of Castletaylor, near Ardrahan, was regarded as one of the finest in the county.
The other new proprietors were the Earl and Countess Mountrath (Sir Charles Coote and his wife); Lord Trimleston (Matthew Barnewall), a leading supporter of James II, transplanted from Dublin; and Walter Blake, the son of Geoffrey Blake of Gortnamona. The Earl of Clanrickard, the largest landowner in the county, managed to retain much of his property.
