Although I have not verified it personally, DAR records and other sources online indicate that David Sloan was born in County Down, Ireland. We know that he was in Wilkes Co., NC in Jan, 1784 when he married Susan Major. His arrival in SC was likely between 1785 and 1787 when he settled in Sloan's Ferry. William Sloan may have been in SC prior to David coming there, based on some land transactions. Hope this helps, Sheila
