Anne Marie Tønnesdatter - til Washington

Anne Marie Tønnesdatter travelled from Norway to America in about 1885. She was born in Klepp 12 March 1857 and her parents were Tønnes Omundsen and Rakel Abrahamsdatter. She lived in Washington and was married to Andrew Nelson who probably died in 1899. Several of her brothers also went to Washington. She was called Mary Nelson in America and I wonder if she had any children. Can she be found in any of the censuses in Washington ?
