I need proof of Isaac Shepherd Nelson and Zilla Norwood's marriage and any document that list their son John Norwood Nelson. Isaac was born in 1795 in Washington County, TN. He later moved to Franklin where he served in the War of 1812. In Feb of 1816 he married Drusilla Zelphia "Zilla" Norwood. They had a son in 1818 named John Norwood Nelson.They moved from here to Marion County, Al and then on to Walker County. I am desended from this line. John married Lousia Cathern Davis. Any documentation of Zilla and Isaac's marriage, a Franklin County census of the family including John Norwood Nelson or any other doucment would be a tremendous help. I am needing this proof for my SAR application. Any help or lead would be greatly appreciated.
