Well, looking again at the 15th Census for 1930 and the 16th Census from 1940...
Axel R Henrickson with his wife Hanna C are listed. In 1930 Elsie R, Richard J and Gordon D is the list of that family. And, darn'it :) , Axel is Carpenter Contractor in the Industry Buildings.
In the 1940 Census only Axel, Hannah, Richard and Gordon D in the family. So Elsie R seems to have either gotten married or moved somewhere. As occupation Axel stil is Carpenter / Buildings.
So, it can very well be the person you described above. Allthough I guess I don't have any rights to a Bungalow in Chicago now Big Laugh.
Again, Thanks for this finding!!!
