The 1940 census is now fully indexed and free to search at Ancestry.com. Your group is of the era that they are likely found in the 1940 census. I did some searching for you but found it impossible to distinguish various people of those names based on the data given; you may have more information that will allow you to "sort" them. For example, you may know middle names (e.g. Edward Lewis Thomas).
I did find Wauneta with husband Edwin Calene (their names are unusual, which helps!).
1940 San Antonio, Los Angeles, California Edwin Calene 42 b abt 1898 in Kansas Wauneta Calene 37 b abt 1903 in Nebraska Mary Lee Calene 5 Residence in 1935: Same Place (a question on the 1940 census)
I have to believe that more of these siblings are "findable" in the newly released census; they should be in their 40s and 50s in 1940.
