I have for YEARS been searching for death certicate for James Jones born Virginia around 1828 Married a Sarah Jane Scruggs in Nashville Tn 1846 had child Richard Lafayette Jones 1848 in Nashville, TN and had daughter Mary Jane Jones (Tanley) 1950 in Nashville, TN. They are last on census together in Nashville, TN 1860 cannot locate 1870 and in 1880 Sarah Jones is listed as widow. All family trees have this photo attached it does not say were the photo comes from but if you zoom in on the photo in the right hand corner it has a placecard date 1829 also all the family trees state Sicily and Thomas Jones from Mecklenburg County, VA are the parents, James is listed on 1850 census at the parents but Sarah is not could it be possiable that Sicily and Thomas is not this James Jones parent's" why would he be on their census in VA and married in Nashville, TN with two children and wife. No documents on none of these trees to prove this. I have found death records for the rest of family but cannot find date of death or where James Jones is buried or who for sure who his parents are. Thanks in advance
