I've uploaded one in case you haven't seen a census sheet from 1940 yet:
|Lake Creek Township, Calhoun County, Iowa, Page 5B (E.D. 13-19)|
The image above contains the Harold Whitted residence and lists his wife Helen (Ross) Whitted as his wife. Also living at this residence, according to the census, was his mother-in-law Mary (Stotler) Ross and her son Oliver Ross. The document also contains two spots for supplementary information and as a matter of luck, Harold Whitted is in block 68, so there is some supplementary information about him. Mary (Stotler) Ross is my 2nd Great Grandmother. Not really expecting to see any ground breaking information, but Oliver apparently was visiting from Sioux City. (at the time of the census at least) If you click the image above you should be able to take a closer look at it.
Of the 16 sheets in the Lake Creek township, I found 3 more sheets that had relatives including the Clara and Frank Fowlie family, the Mason and Daisy Ross family and the John Ross Jr. family. I'm expecting to find Floyd Brassfield in Lake City, but I don't have the patience to wait for the website.
