The will of Robert Clugston, of New Burgh, Orange County, NY, made 1845.8.1 and proved 1845.11.13, states that his brother John Clugston was his only next of kin (Orange County Will Book M, page 498).
They were both literate at least to the extent of being able to sign their names, though the will was written down by one of the witnesses, Channaig? F Belknap.
John may be the male age 20-30 in the 1830 census. The children in the 1840 census would be his children. Apparently John and Rachel were away in 1840.)
Letters of administration were given for John Clugston in 1853.6.24 (Book I page 5) Executor: his widow Rachel; Robert Clugston in 1861 (Book J page 248), Rachel Clugston in 1866.4.5 (Book L page 42), executor her daugher Caroline M; and Ann M Clugston in 1867 (Book L page 153).
They are the right age to be brothers of Thomas Clugston b. 1787 of Ballintemple, County Armagh, Ireland. But they couldn’t be, because Thomas’ brother Robert died in Ireland.
