Query: DYE/TAYLOR of Montgomery and Jefferson Counties

I'm trying to locate the grave site of Eleanor (DYE) TAYLOR born May 22, 1774 in Kentucky, died Oct 22, 1841 in Montgomery Co. IN. Her husband Nathaniel Francis TAYLOR died March 26, 1847 in Jefferson County, near Vevay, Indiana. They may be buried close to each other (or more likely they aren't in the same cemetery).

Any help or suggestions where to look will be appreciated.
