According to Glen Miner's Gallatin Co. Cemetery books; most are buried in Crawford Campground Cemetery, which is just west of Ridgway. This is on Campground Road and visible from Main Street going into Ridgway from IL Route 1. This is in North Fork Township, Section 25, T8S, R 8 E.
From the book: Woodward, Emaretta died 1892 age 58 years, wife of G. D. Woodward
son Cliff 1867 - 1947
wife George Hannah 1868 - 1949
daughter Beatrice 1889 - 1913
There is no listing for George in this book.
I did find a listing for a George Dallas Woodward in the IL Statewide Death Index for 22 Nov 1928 in Eldorado, Saline Co., IL. This is not far from Ridgway.
