From the book "Roster of South Carolina Patriots in the American Revolution" by Bobby Gilmer Moss:
Samuel Nisbett From 16 May to 27 August 1779 he served under Capt Andrew Barry.In addition, he served as a lieutenant on foot from 15 February to 15 May 1780 under Capt John Barry and Col Roebuck.At sometime, he was a captain in the militia under Colonel Roebuck.
Robert Nisbett Sr. He served in the militia under Capt. John Barry, Andrew Barry, John Collins, John Nisbett, Samuel Nisbett, and Col. Roebuck from 1 May 1778 to 24 October 1782.
Robert Nisbet Jr. Born in Ireland on March 5, 1766 While residing in Spartanburg District, he enlisted and served at various times from 1 May 1778 to 24 October 1782.He served in the cavalry and the infantry under Capts. John Barry, Andrew Barry, John Collins, John Nisbett (his cousin), Samuel Nisbet (his uncle), and Col. Roebuck.He also served two months as a spy under William Caldwell.Moved to Tennessee.
John Nisbet He was a lieutenant on horseback from 15 June 1780 to 1 June 1781 and a captain in the militia from 6 October 1781 to 24 October 1782 under Col Roebuck.
James Nisbet He served thirty nine days as a horseman under Capts. Andrew Barry, John Nesbitt and Col Roebuck from 16 May 1780 to 1 July 1781.
I descend from the last mentioned, James Nisbet.I am pretty certain that all of the above were related - I just don't know all the connections.The only service record that mentions relations is Robert Nisbet Jr's - and it is interesting that he was born in Ireland.Would appreciate hearing from anyone researching any of the above.
