Seeking information on my 3rd great-grandfather James Brown (b.1821 TN) and his possible relationship to Nancy Brown Sparkman, b. 1825 TN. James married Mary Ann Holder (b.1827 NC) in 1843 in White, TN. James & Mary Ann were living in Van Buren Co, TN in 1850 and moved to Ballard, KY c. 1854. In 1870 Nancy Brown Sparkman, widow of Truston Sparkman, was living in Ballard, KY with a Willam Brown b.1844 listed in her household. This William (b.1844) appears to be the eldest son of James Brown b. 1821. I am trying to piece together whether Nancy & James were siblings or cousins in an attempt to establish James' ancestry.
Nancy & Truston Sparkman were living in Van Buren, TN in 1850 and had moved to Barry, Mo by 1860. The fact that Nancy moved to Ballard, Ky after the death of Truston in Missouri & the fact that James' son William is living in her household in Ballard, KY seems something more than coincidence.
Any info related to these two Browns possible ancestry would be greatly appreciated.
