Spanning the River

There are two volumes of the book, "Spanning the River". This is a set that the Dewey County (Oklahoma) genealogy/history club put out with stories about families that settled there - before and after statehood in 1907. We got to know that the wife of a dear customer of ours (Dad and I were auto mechanics and Dad had worked on their cars for years!) was a distant cousin! Well, we ordered the two books through Mrs. Day and I started reading. We thought someone had Dad's aunt mixed up with his Grandmother, but they weren't - and we found out the real name of the Grandfather for Dad's two cousins! It all fell into place. Stories I had heard were confirmed. Stories of different families were validating the other. Even a letter from one of the editors revealed some more history of our family. Now I just need to get a hold of the 1900, 1910 censuses to get a household picture . . .
I need to find:
What is Thomas V 'Pune' Addington's wife's name ?
Where is Effie Mae (Ridley) Addington buried ? (burial records search)
Where were Henry Bascom Ridley and family ?
Was 'Aunt' Annie Dodson at the Shanahan Ranch ?
Now if I could get something like that trickling down from Oregon or Washington state to place more of the family . . .
