According to his death record he was temporarily interred at Pleasant View Cemetery in Randolph VT and finally buried in Mt Pleasant Cemetery in Stockbridge VT. However his surviving spouse was not Ella Emma (Pratt) Proctor, it was Gertrude Kilgallen.
Ella Emma (Pratt)Proctor died 31-Jul-1976 (not in 1978 as your post indicated) at Gifford Memorial Hospital in Randolph Vermont and was buried in Mt Pleasant Cemetery in Stockbridge VT on 12-Aug-1976.
I can not find a death record for Ida Mae (Hazelbaker)Proctor anywhere in Vermont nor for that matter her husband either.
Hope this helps.
