I am searching for information about the same Wm R Finney. His son Valentine Crawford Finney (1876-1943) is the father of Benjamin Morris Finney (1900-1968). And Ben M Finney (AKA Vernon) married Ilma Cassity in 1923 in Wise County TX. They had a son named Sherman L Finney (1925-2005).
Like you, I'd like to find out who William R Finney's wife was and who his parents were.
Your post is quite old, did you ever find out any information?
