Tandberg slekten på Ringerike

Han var som 20 åring bestyrer af Storøen i Holtsfjorden i 2 år.

I 1834 købte han gaarden Septon i Søndre Land for 3000 Specidaler plus senere 500 Specidaler i odels løsning. Ifølge brev fra sin fader Gulbrand Eriksen Tandberg havde gaarden "god skov (mindst 5000 maal) og føder årlig 6 hester, 30 stykker fækreaturer,50 stykker gjeter og havde godt fiskeri. desuten Bordsaug, tjærebrænderi og godt bygget gaard". Septon tilhørte tidligere Sorenskriver Meidell. Han var en dygtig landmand.

Han fulgte sin fader og Statsraad Riddervold, som kusk og tjener på en reise til Stockholm. Denne reise blev et kjært minde for ham og han fik ved hjemkomsten en 20 fr. i guld af Statsraaden, som nu eies af sønnesønnen Erik.

Petrine Pedersdatter Lille Aadnes, born 1816, married Erik Gulbrandsen Tandberg of the Setton/Septon farm in Fluberg in 1837. Erik Tandberg’s first wife Sarah Andersdtr Kragstad died in 1829, leaving a daughter Berthe who in 1851 married Andreas Gaarder of Østsinni (ancestors of Landings Lag members Charles Gorder, and Ann Edwards and her children). Erik was raised in a large, interesting family from the Tandberg farm in Ringerike, Buskerud. Boka om Land V, Fluberg, missed Erik’s first marriage to Sarah, but in Boka om Land XV, Østsinni, they do list him as the father of Berthe Tandberg who married Andreas Gaarder in 1851. (Left is the monument of Erik and Petrine at the Fluberg church.)
Erik moved from Ringerike to Land when he bought Setton in 1834. Erik and Petrine had ten children, Gulbrand was the first born in 1838, married in 1868 to Marthea Olsdatter Askvig. Gulbrand and Marthea had children Petra, Gyda, and Erik born 1876. This Erik married in 1899 Marie Elisabeth Kjøstad born 1872 and had children Gudbrand born 1900, Jørgen, Minnie and Kirsten.
