"Duncan Ochiltree
Duncan Ochiltree was one of the original signers of the Meckenburg Declaration of Independence.
Although Duncan Ochiltree was credited as being one of the original signers, his name was removed from all subsequent accounts of documents because he became a traitor by becoming a Quartermaster for the British. He owned a mercantile store as well as land, but he knew his fellow citizens would punish him for his change of heart and political leanings. According to Alexander, he begged John McKnitt Alexander to spare his life and protect him, after the British Army left the Charlotte area. John promised him protection while he was in his own home, but he advised him to leave the area immediately. Ochiltree reportedly fled to Wilmington and later moved to Florida.
John McKnitt Alexander told his slaves, Cato and Ruth, to burn the stockyard and barn rather than give food and provisions to Ochiltree for the British. When this event he feared happened, Cato and Ruth did burn the building and year’s worth of farm work to ashes.
King, Victor C. Lives and Times of the 27 Signers of the Mecklenburg Declaration of Independence of May 20, 1775. Charlotte, NC, 1956."

I just happen to be searching for a Carolina Scot !! Duncan Ochiltree came to Carolina in 1739, with brother David..He married a Vera fleming. His parents were John Ochiltree and Katherine McLea. Duncan was born in Glascow in 1709.
Duncan was a Loyalist. He was Merchant. He lived in Mecklenberg. He assisted another gentleman in forming the first Grand Masonic Lodge there, he was one of the signors of the Mecklenberg Declaration of Independence a year before the American one was drawn up. The English were invading and the citizens were afraid he would engage the English to buy his wares and that he would turn coat against the colonists..The men erased his name from the Declaration and ran Duncan out of town...to get on the Yadkin and never return.
Next May is the 237th anniversary of the Declaration. My project is to do a bio of Duncan Ochiltree....I have found everything I need except for a death record. If he did not die that night on the Yadkin, He may have changed his name...would he have taken his mothers maiden name or his wifes maiden name..:
