Treston Family History & Genealogy

Griffith's Valuation Threston/Treston
It has been researched and concluded that the Treston families found in Griffiths Valuation of Ireland are the formerly ennobled Threston family of England (who are referenced on this site) and the decedents of Threston/Treston family that later moved to the United States (as well as Canada) and settled in Pennsylvania, Illinois, and, other parts of the country.
Griffith's Valuation
Quoted from

"Irelands Valuation office conducted its first survey of property ownership in Ireland from 1848 to 1864. This survey became known as "Griffiths Valuation" after Richard Griffith who was the director of the office at that time. The survey was used to determine the amount of tax each person should pay towards the support of the poor within their poor law union. This involved determining the value of all privately held lands and buildings in rural as well as urban areas to figure the rate at which each unit of property could be rented year after year. The resulting survey was arranged by barony and civil parish with an index to the townlands appearing in each volume. Griffith's Valuation can be used as an excellent census substitute for the years after the Great Famine as censuses prior to 1901 were destroyed."

"The name Treston appears in the Claremorris and Ballyhaunis area of county Mayo from the 18th century. They appear to have been closely associated with the Dillons of Feamore, parish of Bekan, barony of Costello. At the time of Griffith's Valuation the Trestons held 3 townlands in the parish of Kilcolman and 1 townland in the parish of Mayo, barony of Clanmorris, previously part of the estate of Patrick Kirwan of Dalgan and also a townland in the parish of Bekan, barony of Costello, county Mayo and a townland in the parish of Kilgefin, barony of Ballintober South, county Roscommon. The representatives of John Treston of Carrownedan advertised for sale 1625 acres in counties Mayo and Roscommon in the Landed Estates' Court in 1865. The county Roscommon lands were in the baronies of Ballintober South and Frenchpark. In 1876 four Treston brothers held almost 1900 acres in county Mayo. At the time of Griffith's Valuation James Treston was one of the principal lessors in the parish of Kiltullagh, barony of Castlereagh. In the 1870s James Treston of Tulrahan, Ballyhaunis owned over 180 acres in county Roscommon."

"At the time of Griffith's Valuation George Walpole was the main tenant on the lands of Trilacroghan, parish of Kilgefin, barony of Ballintober South, county Roscommon, part of the Treston estate. 172 acres of Sheehaun (Morton) in the parish of Kilgefin, county Roscommon, plus the lands of Springfield and Carney Park, barony of Lower Ormond, county Tipperary, the estate of William Calvert, were advertised for sale in June 1866 on Calvert's behalf and as trustee for sale for George and Joseph Walpole. The Bolton sale rental of 1854 records John Walpole as tenant of these lands. In the 1870s George Walpole of Castlenode, Strokestown, owned 694 acres in county Roscommon and smaller acreages in counties Tipperary, Offaly and Laois. George Walpole held land in the parish of Kilbarron and Robert Walpole held land in the parish of Finnoe, both in the barony of Lower Ormond, county Tipperary in the mid 19th century. George held his land from the Marquess of Ormond. William Walpole of Salisbury, Athy, county Kildare, owned 615 acres in county Tipperary in the 1870s"
