John, it has been quite awhile since you posted this so you probably already have this info, but here goes anyway.

Rhoda, my g grandmother, was actually the daughter of Jeffrey Treat and Mary Burgess, who had three other children, Clinton, Louisa, and William.

Rhoda married George W. Stevens on 22 Jul 1886, in White County, IL. They had nine children including my grandmother Pearl Pauline Stevens.

I have quite a bit of info on the Treat side, where I am stumped is on George's family, in that I can't find them.

Email me and I will provide what I have and I will be eternally grateful for any pieces of the puzzle you can provide.
