- The Thorngates were originally from Gosport in England. Griffith's Valuation shows that James Thorngate and his brothers bought some of the estate of the Blakes of Doonmacreena in the parishes of Crossboyne and Kilvine, barony of Clanmorris, county Mayo and some of the Abbeyknockmoy estate, county Galway of the Blake Forsters. P. Lane writes that the Thorngates also bought portions of the estates of Geoffrey Davies in the barony of Killian and Edmond Concannon in the baronies of Dunmore and Dunkellin. By far their biggest purchase was in 1851 when James Thorngate purchased the Castle Ffrench estate and lived there until the 1860s. The estate was sold, after Thorngate's death, to James Crooke, for whom Daniel Churcher acted as agent. William E. Churcher and George Churcher of Southampton were the trustees of the estate of William Thorngate and much of the Thorngate estate appears to have been in Churcher possession by the 1870s. At the time of Griffith's Valuation James Thorngate is recorded as a land holder in the parish of Rahara, barony of Athlone, county Roscommon.
- In the 1870s James Crooks of Castle Ffrench and Gosport, England, owned between 2,000 and 3,000 acres in county Galway and 1,001 acres in county Mayo, which he purchased following the death of James Thorngate.
