Corie,I checked some internet genealogy sites and found William Wallace Parcher on Rootsweb.com; Ancestry.com; and LDS family search.
I am also researching the Parchers, unfortunatly I have nothing on your gggrandfather.The sites I found says he was born in Rockford, Blount Co., TN ; 9 May 1867, married 11 Jul 1886 to Mary Catherine Foster b. 19 Oct 1869 in Rockfort, Blout Co., TN d 20 June 1961. D/O John Foster and Mary Ann Stevens/Stephens.Mary was 1 of 12 children, her father was 1 of 22 which 20 grew to adulthood.
Do you know who William's parents were?I have found Parchers in Blue Earth, MN.There is a book "Elias Parcher and Some of His Descendants", by Elizabeth Parcher Walker.She may have some copies.Email me if you are interested in her address.
