I am a Sabo....my grandfather Joseph Andreas Sabo came over from Norway with his family (His mother was Ella Sabo and his father was Andreas Sabo). It was spelled SÆBO in Norway, they dropped the "AE" to use only english alphabet and now it is SABO. I know that some of the same family took the Lilloeren name. They all came from farms in Sognefjord, near Vik. My grandparents and family came across to the Ballard and Arlington towns in Washington. I visited several years back and found the gravesites behind a small church.
I have more information about my family, but would have to dig it out of a box somewhere. Anyhow...if it helps, and if anyone can add to the lineage I would be interested.
