Josiah DOWNEN is my 5 x great grandfather and I have found information that leads me to believe that he was most likely "Scots-Irish", the people descended from the lowland Scots planted in Ulster, Ireland.I bring this up because the "History of the Downen Family 1777-1970" speculates that the DOWNEN name is either English or Irish.
"Between 1780 and 1782 during the Revolutionary War, Josiah [DOWNEN],Sr. served in the South Carolina Militia under the command of General Andrew Pickens, American Revolutionary Partisan leader, who formed armed bands to harass the British in South Carolina. Josiah was sent out on a detachment under Colonel Hays to encounter the enemy and was knocked from his horse and was badly hurt." Source: South Carolina Department of Archives and History, loose papers in folders: "For Militia Duty - Reference - AA2014, pages 1U through 2U.
From the information cited below it would appear that the Militia under General Pickens (of which Josiah DOWNEN was a member) were Ulster-Irish (Scots-Irish):
"Or take the battle of Cowpens. Daniel Morgan was in command, with a mixed force of regulars, militia, and dragoons. He and his men killed 100 British, wounded 200, and took 500 prisoners with a large quantity of military stores. These numbers sound small in our ears, but no large armies were engaged in this war, and figures like these represented a crushing British defeat. For this victory, Congress gave General Morgan a gold medal, General Pickens a sword of honour, and Colonel Howard a silver medal. Morgan and Pickens were elders of the Presbyterian Church, and all three, as well as the troops they commanded, were Ulster-Irish." Source: "Ulster Sails West" 1950-1996, by W. F. Marshall, p 35
Note: "Ulster-Irish" and "Scots-Irish" are synonymous.
