The Maine marriage records on Ancestry have the original documents up now:
http://search.ancestry.com/iexec?htx=View&r=an&dbid=...The parents for Malvina are recorded as George BELAND (living in Fort Kent, born in Canada) and Celine PINELT (probably PINEAU/PINEAULT)born and living in Fort Kent, Maine.
William's last name is recorded as DEPRE; his parents are listed as Marsal DEPRE (living in Wallagrass, Maine, born in Canada) and Susan CORBIN (living in Wallagrass, Maine, born in Fort Kent, Maine).
Hope this helps.
