I am looking for information on Joseph E. Akers (born 1795) and Elizabeth Heard (born 1805). The couple had five children: Sarah, Catherine, James, Mary Ellen and Marion. The children were born in Missouri and it appears that Joseph and Elizabeth both died in Ray County, Missouri. According to a history of Ray County written in 1893, Joseph and Elizabeth were both raised in Kentucky, though it is unclear if they were born there. They then traveled to Missouri.
I am looking for documentary evidence that attaches Mary Ellen to Joseph and Elizabeth and then for evidence for the lines past Joseph and Elizabeth. Thanks!
