I just came across this forum while looking for information on my ancestor Logan Kinder and his wife Jane Eakin. While our family history ends (at least the part that my mother and her sister has concerning the Kinders) with Thomas Benton Kinder, born in 1842 in Cape Girardeau County MO.
In doing research using the LDS FamilySearch resources, I managed to find an Ancestral File of Thomas B. as the son of Logan and Jane, although that file ends there, and does not include information about the marriage, children etc. of Thomas B.I also found some information in the International Geneaological Index (IGI) that puts Logan and Jane's marriage in Cape Girardeau Co. MO in 1841. From this information, and other records I could find there, it appears that both Jane and Logan were born in North Carolina, Logan in 1820 and Jane in 1822. She was the daughter of a William Eakin (spelled Aiken in one source) and Jane McBride.
Your information is different, so I was hoping that we could compare notes and figure out what's going on. So far as I can tell, from census information, etc., there was only one Logan Kinder in CG, MO during that time (1840s-1870s). I'm hoping that your information is more complete and more checkable than the online stuff.
