This should work for any county or surname.
Type in "Census, Clinton County, Iowa" on your search engine.
You will get a list of census records at "Ancestry.com".
Scroll to the bottom and you will get a box into which you type the surname "Hass", state "Iowa", county "Clinton".
I received over 130 Hass individuals who lived in Clinton County with their birth years and on which census they can be found. I quit counting at 130. There were more.
