- 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.
- By 1876 Emanuel Churcher of Gosport, Hampshire, England, had bought some of the estate of James Thorngate in county Galway, including Castle Ffrench as well as Thorngate's estate in the parishes of Crossboyne and Kilvine, barony of Clanmorris, county Mayo. He still held untenanted land in the Crossboyne locality in 1906. Thorngate and Churcher were both natives of Gosport. In the 1870s Churcher owned almost 8,000 acres in county Galway, 1,400 in county Roscommon and 1,633 acres in county Mayo. Part of the Churcher estate in county Galway, amounting to 1,633 acres, was sold to the Congested Districts' Board in March 1912, with a further 978 acres in that county going to the Board in February 1915. 1,546 acres belonging to William E. Churcher in county Mayo were sold to the Congested Districts' Board on 23 Oct 1913.
