I am searching for any reference to Isaac Young b. before 1774 (according to census data). He died sometime between 1830 and 1839, judging from a lack of census records and a deed referencing his widow in 1839. He appears in Williamsburg Co., SC in the 1800 census and buys land in 1804. He possibly had a father or grandfather named George and brothers named William, James, Henry, Arthur or Washington. He may somehow be related to a Carney and an Addleton or Addington, because the names appear as middle names for his grandchildren for which there seems to be no connection to their mother's family. Any help would be appreciated. Melanie Young
