Hi again!
I checked my information. I actually have a note in my records that say my Susannah Donohue (married to Walter Creason) could be the same as Susanah Mahan. However, I believe it is my own note and was purely conjecture at the time. However, I do know that our Henry Calhoun Creason died in Boswell, Oklahoma...a strong case for at least relation to your Henry! I also have Walter's birth place as Ray County, Missouri. I am not sure how I got that, though.

What I wonder is whether Henry Calhoun Creason could have had a second wife (or third since I do have him possibly married to a Miss Fox after being married to Martha Elizabeth Agee...she died in 1885/1886 in Arkansas)

Do you have anything more concrete?
