I have information indicating that they are brothers, I am a descendent of their brother Samuel. I am not sure if William went with them to Arkansas at the same time but believe he joined them later. I have more on this family to share. My data shows the children of Joseph to be as follows: The children were as follows:(1) Rebecca, b. ca. 1798, (2) Elisha, b. ca. 1799, (3) Joseph, Jr., b.14 Feb. 1801, (4) Nancy, b. ca. 1802, (5) William, b. ca. 1805, (6) Sally, b. ca. 1809, (7) Samuel, b. ca. 1814, (8) Rachel, b. ca. 1815, (9) Henry, b. ca. 1816, (10) Ennis, b. ca. 1818, (11) Charles, b. 16 Jan. 1821, (12) George and (13) Lucinda.
Samuel and Charles married the Mann sisters Samuel married Mary Susan Mann in 1837. Charles married Sarah Jane Mann in 1842.
