Nevertheless, his mother, Helga Holmboe, was born in central Norway, in Trøndelag, while his father was born in Østfold, in the south. Galtung has been married twice, and has two children by his first wife Ingrid Eide, Harald Galtung and Andreas Galtung, and two by his second wife Fumiko Nishimura, Irene Galtung and Fredrik Galtung.[8]
