Hei! I've just checked Olu Rugh, buthe doesn't help much. For one thing he doesn't record a Granum in Nordre Aurdal. Heonly shows 2 in Søndre Land, one each in Vestre Toten, Østre Toten and Vestre Gausdal. Of the two in Toten he implies that the '-um' is a shortened form for 'heim' As to the others he maintains that they are new names but in one case a reference to the dative form. All too frequently, Oluf Rygh disappoints. Olaf. > Family legend has it that the name originated in Roman days, and is Latin > for grain.
