Bengta/Bungta Anderson b. Sweden abt.1830 +/-

Trying to locate any family of, or person with any knowledge
of a Bengta or Bungta Anderson who was born in Sweden around 1830. She married a Hanson. This family had at least two children, Walter and Anna born in Sweden prior to them going to Denmark in the early 1850s. When they got to Denmark, they changed the spelling of their namd to Hansen. There was another "son" Andrew with them in Denmark, but it is unknown if Andrew was (1) born in Sweden, (2)born in Denmark or (3)was a son of a relative. Bengta, along with Walter, Anna and Andrew immigrated to the USA around 1865.They traveled through Iowa prior to ending up in Utah.Walter married in Utah, work a while in Idaho and then around 1870 +/-, he, his wife and sister Anna moved back to the East Central Nebraska area. Bengta/Bungta remaind in Utah along with Andrew.Nothing was learned of Bengta or Andrew after this point. I am descended from Andrew and have more or less hit a brick wall while trying to find out any more information about him....any help much appreciated.
