Regarding Hayden Jackson (b.abt 1816) -- I have found the following information: Hayden (Haden, Haydon) Jackson was married to Louisa WILLIAMS 28 Mar 1838 in Ray county. It was performed by Jacob Warriner in the Church of Christ.
Name: Haden Jackson
Marriage Date: 28 Mar 1838
Marriage County: Ray
Spouse Name: Louisa Williams
Missouri Marriage Records, 1805-2002 (ancestry.com)
Also listed at the following website:http://files.usgwarchives.net/mo/ray/marriages/hist901.txt
I think I have also found Hayden and Louisa in the 1840 census, living in Marion, Buchanan, Missouri. He was enumerated as Haden Jackson. In the household are the following, in parenthesis- my estimation of family members: 1 Male under 5yrs (Garrett); 1 Male 20-29yrs (Hayden); 1 female 15-19 (Louisa J Williams Jackson).
I am interested in any additional information on this family!
