The clever Hamilton County folks determined this was a picture of a party at the home of County Supervisor Hampton Terrell Wilson. From family trees I found:
Birth Jun 1859 Indiana, United States
Death 18 Apr 1939
Father James Wilson (1816-1876)
Mother Nancy E Hayden (1831-1904)
Spouse Elizabeth Ann Philp (1860-1941)
Married 1885
Children Richard J (1886-1957)
Zoe Blanche (1888-1978)
Carrie (1890-1976)
George Percy (1894-1967)

I am emailing you the scanned picture. If you are related to these folks, could you please post the photo on Ancestry? Since this is not my relative, I can't figure out how to post a picture with no related name tags.

thanks
