Gerald - Bill was my uncle and his father was also William A Dedman (went by WA). The other postings confuse the two.
Bill was buried in Sandy UT - here is a link to his obituary http://www.deseretnews.com/article/550558/Death--William-A-D...
WA is buried in Ashton ID.
I ran across your post when doing research for a family reunion.
Hope this helps.
