I have John Elijah O'Bannon (1865-1937) of Madison Co, MO born to Francis (Frank) O'Bannon (1823-1911) and Emma Jane Hill (1838-1880).
I have John Elijah m. to Mary Frances Menley (1877-1961) To this union I have 8 kids--5 girls, 3 boys. One of the girls is indeed Sadie May (b.1901, d. when?) and one of the boys is indeed John Frank (1915-1975). I do not have wife and kids for John Frank. I have names and descendants for the others of Sadie's and John's siblings.
As for for Sadie Mae, all I have as her husband is a guy named DeJournet (first name unknown). I have no Bollingers for this line. Perhaps Bollinger was a later husband of Sadie Mae?
I do have Bollingers married to O'Bannons in collateral lines--they probably came from Bollinger County, MO--adjacent to Madison County where the O'Bannons lived.
Although Cherokees intermarried into O'Bannons in other collateral lines, I cannot guess who of the above line would have contributed Indian genes. Perhaps Emma Hill? Certainly not any of the O'Bannons--Elijah was four generations removed from Ireland and the O'Bannon males married women of mainly English surnames.
If you will contact me at firstname.lastname@example.org
we can discuss these differences more readily.
Good hearing from you. Would certainly like to add more to this line. (John Elijah's father Francis was brother to my great grandfather William Isom, and I have a photo of Francis in old age).
