Your Napoleon Jouett was a son of Thomas Jouett, wife unknown to me, born ca 1809 in TN; and grandson of Thomas Jouett and Hannah Tate. Since Hannah was my GGGG Aunt, that makes us cousins. Thomas, Napoleon's father, went to the Republic of Texas in 1830 and became prominent citizens of Fannin County, Texas.
Hannah was a daughter of John Tate and Sarah Street who were my GGGG grandparents.
