Anyone have documentation for this relationship?
Found the relationship on some of the children, but it does not tell who "Nancy Brandenburg"
I think this is a different Elijah. The 1860 census shows:
Elijah Creech born 1809 in VA, living in Owsley Co., KY AND
Elijah Creech born 1810 in VA, living in Harlan Co., KY.
In 1860, the Owsley Elijah is married to Louiza, with kids John, Elizabeth, Martha, Mary, Amanda, Alexander, and Jane.
In 1860, the Harlan Elijah is married to "Sary," with kids: Nancy, Elijah, Katherine, Elizabeth, and Ira.
In 1850, the Owsley Elijah is married to a "Nancy" (perhaps Brandenburg) with children: Sally, John, Martha, Mary.
In 1850, the Harlan Elijah is married to Sally, with children: Evaline, John, Mary, Jane, Jonathan, Rebecca, Sally, Elijah, Catherine.
The Harlan Elijah is Elijah Lee Creech, son of Jonathan Creech. Nancy is married to the Owsley Elijah, which is a different line.
