Thanks for the answers. It was good to find out about Ragnar Thillesen, but I was sorry to find out that he died without family. Seems like it will be difficult to find out more about Thille and Ragnar Thillesen. One way is if it is possible to find an obituary for Ragnar Thillesens father Thille Thillesen or Thilles wife Rose. They both died in Los Angeles, he on the 4 of Februar 1952 and she on the 27 of Oct 1957. Do anybody know if there were orbityaries from that time?
