Jennifer, In the 1910 census there's a Henry Ertz, age 46, born WI, married twice, living and farming in McCully Township, Boyd County, NE. Wife's name Justine 32 married once, born in Germany, kids Lilly 13, Edward 11, Lorens 9, Louis 5 all born in Iowa and Frankie 3 and Leonhardt 7/12 both born in NE. This family looks like the family you're looking for. In the 1920 census the family was still living in Boyd County, NE, and Augusta was listed there also. Pete
