I answered Sam Long twice but can't seem to get thru. Don't know if this helps, but John Read Long d.1819 in Abbeville,SC with a will naming his son Harrison Long (who d. without wf or chn. 1830 with a will) and a deceased dau. Lucy Long Swancy whose husband I gather was Dr. Samuel Swancy. Later in Lowndes CO. MS.deeds, where some of this line went, was a Robert Swancy -also from Abbeville. (Lucy's son?)There are 2 more sons of John Read Long: Reuben and Nicholas, whom I haven't found, but they could be clues to your Harrison SWANCY Long (dates?) if you can find them! A sister to Reuben & Nick was Elizabeth "Betsy" Long who m. Joshua Shirley and had HARRISON Shirley m. in Pickens AL Cynthia Bennett and moved to Pontotoc Co.MS where they d. An uncle to your Harrison?
