Thomas Barnes was born in the 1620s, probably in Derbyshire, England.
He was a Lieutenant in Oliver Cromwell's army and was granted lands at Grange (Kiltown and possibly also spelt the same as the county) in the south of County Killkenny, and at Donore (or Donover) near Moynalty in County Meath. These land grants were confirmed by Charles II in September 1666.
He married but his wife's name is not known. She was likely from Derbyshire as tradition says three young sons joined their father in Kilkenny.
As understood (this needs more research), the Grange is a place (?civil parish) near the town of Kilkenny (may also be spelt "Kiltown") in the county of Kilkenny, Ireland. It is about 135 kilomtres southwest of Dublin. Donore (or Donover) is outside the town (?village) of Moynalty in County Meath to the northwest of Dublin. The accompanying Google map shows both Grange and Moynalty with the "directions to Dublin" to orient the viewer.
The name of Thomas' wife is unknown. Whoever she was, it is thought that she, too, was from Derbyshire. She and Thomas had the following children:
Thomas Barnes may have died in 1684.

 Files of Barbara Paterson (née Barbara Carolyn Boake 1927-2009): Barbara's extensive notes on the Barnes family were the start of this biography. These contain a hand-written family tree. The author appears to have been “Arthur ?? Barnes [middle name not legible], 1969” In the upper left-hand corner of the chart: "Rough trial draft from data at Westland Moynalty Meath, four courts, Kings Inn, Castle Dublin, books, letters, etc. Final copy with additional information and refrences [sic] to document may be made later." . This chart uses the phrase "By tradition, was born in Derbyshire . . ." It also has the year 1684 written beside the words "His will . . "
 Bomford, Peter, “The Irish Bomfords 1617 to the Present” available at http://www.bomford.net/IrishBomfords/Chapters/Chapter25/Chapter25.htm "The first Barnes to come to Ireland was Lieutenant Thomas Barnes who probably came from Derbyshire. He was granted at the time of the Commonwealth, lands at Grange (Kiltown) in the south of Co Killkenny, and at Donore (or Donover) near Moynalty in Co Meath. These land grants were confirmed by Charles II in September 1666. He had three sons and two daughters."
 O’Hart, John (?1887), “The Irish Landed Gentry when Cromwell came to Ireland” pg 4122-412: In this appendix there is a list of soldiers “addressed to the Court of Claims, who claimed as, or in right of, soldiers serving in Ireland in the Commonwealth period ; and the Counties mentioned in the Eeports.— See Records of Ireland, Vol. marked "1816-1820;" pp. 249-300. “ One of the entries is: "Barnes, Lieut. Thomas, Meath and Kilkenny" Presumably this means that a Lieutentant Thomas Barnes was given land (?or had land) in the counties of Meath and Kilkenny.
