I agree with Erik. We can't help until we catch up with what you know.

I did find an old message board thread that was discussing j James Franklin Shamblin: https://www.ancestry.com/boards/surnames.shamblin/228/mb.ashx
You have to keep clicking on the "Subject" part at the bottom of the messages to see the next message and there are two pages.
It has a few tidbits like he had a store in Oklahoma and was trading with the Indians and also sending goods to trade back East. And that he was killed by a Jersey Bull. That page has him living from 1860 to 1933.
Also there is an old Genealogy.com message board that has some Shamblin information on it. It has a James Franklin Shamblin (son of Benjamin Conley Shamblin and Estle Thursey Moore) who was born February 23, 1925 in Charleston, WV. Then if you follow that tree up it goes back to a Brian Chamblin who claim descent from the Earl of Tancarville in France. It also mentions that they believe the Y DNA halplogroup to be R1b1c9*.

There is also an index page here: https://www.genealogy.com/ftm/s/t/r/Sandra-S-Strickland/WEBSITE-0001/UHP-Index.html
and while did not see James Franklin Shamblin b. 1860 on the index one would assume that he may be connected to this larger Shamblin family.
Looks like there is also a Family Search profile started for James Franklin, though it is not connected up to anyone but his first wife.
