Yes this is the same Uda. We "assume" that Samuel died between 1917 (last recorded in Washington) & 1834 when Uda remarried. She claimed that she was a spinster at the time of her marriage to Olaf.
We cannot find a death for Samuel in Canada or the USA.We cannot find him before 1912 when he married Uda. We cannot find his parents, Edward & Ella.
