Looking for information on the following:

Jas D Chewning married Elizabeth had Jerdron and

Robert Chewning (dob abt 1866) who married Cathrine Browder (dob abt 1859)

looking for any information concerning the daughters Carrie L (abt 1888) and Lizzie V (abt 1890)

Both are said to have been adopted from an Indian reservation and am trying to find out as much info as I can for my grandmother who is now 87. Any help would be greatly appreciated.
