Susan, I am in Salt Lake at the family history library trying to track down Mary McDuffie's husband, M.C., as shown on the 1860 census in Lauderdale Cty, MS. Have not been able to find their marriage with Mary or death or birth records on both, even though they list N.C. as birth state. I have been working on this on and off for 15 yrs. Do you have any info on Mary (death, burial, husband)? There is some speculalation that she might have married John (on the 1850 census with similar kids). Maybe John died and she married M.C. and had Murdock Jackson. Not sure who is Josephine's dad?? Also, there is a Kathy Upshaw (or something like that) that is reseaching Nunnellys. Go to GenForum to see if you can find her postings. Think she has one on Ancestry also.
