"Caple" in Indiana @ 1860/80:

Does anyone have information on the Indiana Caples? I am seeking information on this family in order to find who Selvia Caple (maiden name unknown)were. She was born 1866 in Indiana and her husband's family were too according to the 1900 Arkansas census. Their son was named William and was born @ 1880in Arkansas.
Even if you don't have the "Selvia" I would like to locate about where in Indiana the Caples lived.

Thanks! J. V.
