I found my great-grandparents, John and Mary Huigens in Creighton, NE on ancestry.com:
I then found my 13-year-old dad with his family in Sheridan Co., NE. The census taker spelled the name Higgins, but that's them all right. I'm surprised to see that my grandfather had completed 2 years of high school. That's unusual for a farm kid back then.
