Relatives of my great grandfather Sebjørn E.Rustan

I'm looking for relatives of my great grandfather, Sebjørn Engebret Rustand(b. 1836 in Nore County at Buskerud(NORWAY). Sebjørn went by ship to America in 1882. His son, named Christian Rustand, came there two years later. Father and son MAY have taken the name of Solum, which was probably distorted from Sole in Eggedal county(also Buskerud). Grateful for your assistance! Ms. Anne Merete Kruge 3014 Drammen(NORWAY) [email hidden]
