I looked in our family tree to see what I had on the Ross family.Here is what I came up with.This information came from Merrell McAmis.I lost contact with him.The last time I wrote to him was in 1990 and he was living close to St. Louis Missouri.
William N. Ross born about 1778 in Virginia and died about 1824 or 1825 possibly in Stewart County, Tennessee.He married on 31 dec. 1807 in Greene County, Tennessee to Sarah McCamish.William Ross is the son of Isaac Ross.Sarah McCamish was born about 1790 and died either 1870 or 1880 in Texas and is buried in Bowie County Texas.Sarah is the daughter of Thomas and Jane McAmish.William and Sarah had two children. 1.Akin N. Ross born 16 Aug. 1808 in Tennessee and died 18 Oct 1867 Bowie County Texas.He married Martha Ann Lumpkin on 5 March 1836. 2.Caroline Elvila Ross born 1815 in Tennessee and died after 1880 in Texas.She married Larenzo Bartlely on 5 Mar 1835 in Greene County, Tennessee.
I have no other reference for this information except Merrell McAmis.If you could locate him he could most likely tell you where he got the information if he is still working on the family tree.I hope this gives you some clues.Good Luck.
