Looking for their grandparents.

You would be much more likely to get helpful replies if you provided a bit more information.

We can probably assume that these folks lived at some time in Hardin County. But when was that? Were they born there, and if not where did they come from?

Also, if you are looking for their grandparents, I assume you know who their parents were? Who were they?

Rev. William Albert Banks was born in Mississippi on July 5, 1865 & died on Jan. 13, 1941. He was a Methodist circuit preacher in Kentucky and Tennessee. His wife, Martha Paretine Hale, was born July 21, 1865 in Tennessee and died on March 2, 1934 in Tennessee. I'm looking for William Albert's "grand-parents". William Albert's "parents" names are James E. Banks born 1805 in S. C. & died aft. 1870. His mother is Zeoury (Missouri)Annie...don't know her father's name but he might be Vincent Cooper, but can't verify that. I mentioned Rev. Banks first only because he might have more history recorded than his grand-parents. I have researched several years on this without any luck.
Many thanks!
