Was looking at your harriet Jordan. Are you sure she wasn't married to a Jordan, rather than being a Jordan? Reason asked, is she married Needham in 1848 and 1850 census has her age 35. Not many women waited to marry until their 30's back then. some yes, but not usual. Also you have needham marrying a Margaet Dill, and I found a marriage for him in 1835 to to a Isabel Barfield, so he may have been married 3 times, or there were more than one Needham McLendon.
