Marge, am posting here so others may read and add some info and you should be notified of this post.
When looking at my gfathers 1920 census (Willliam Wynn) he is living with one of his daughters (Georgia Nichols) and her son (John E. "Johnny" a Pearl Harbor Arizona survivor) on Depot St. in Knoxville, IA.
Next door to them is a couple, with names Erma or Emma and Chas Liikee or Lickee. A "Y" from the house owners name (Mabel Hays) is over the i or c, they are listed as boarders. Also, there is the extra e on the end of the name.
Perhaps Chas is Leopold's brother, cousin, etc. ?
I just noticed this, and didn't print out the entire census page, but will try to get more info about them.
