Robert Risch's Family Home Page

I am searching for the surnames Risch, McClure, Clay, Cooper, Hanavan and relations to.
Risch and McClure came from the Pennsilviania region in the late 1800's. The Clay and Cooper from Idaho also late 1800's to early 1900's. Hanavan from California early 1900's.

I'm hoping to find any information and possible relations involving these names.
