One comment (perhaps ignorance on my part?)... are you sure Ellen married Sie McKinney (full name: Josiah Henry McKinney, son of David McKinney and Elizia Hoilder)?
Census records show Ellen married to a Henry Ledford... not McKinney. So,
while Sie was Josiah HENRY McKinney, he's not the Henry in Ellen's census records. During those same census years, Sie is shown married to Queenie Bell Frye (They (Sie and Queenie) interred in the McKinney Cem in Mitchell County, NC).
So, perhaps your Ellen married a different Henry?
If you wish to research it.... they (Henry Ledford and Ellen) are in the
1910, 1920, 1930, 1940 census records (all without any children) in
the Allen, Clay, KY or District 5, Clay, KY records.
If you hit a brick wall with Ellen, perhaps this is why. I wanted to let you know .... just in case and I hope this helps... and I hope, in my ignorance of this line, I'm not asking about an entirely different family......... If so, forgive the comment and, please, email me, so I can remove it.
Happy family-histoy hunting.
