The area was originally settled by Germans. The Klein family had much land in the area. The School District is Klein ISD. The Klein area is located within Spring TX. The area near Louetta and Steubner Airline is part of the Klein area.
I assume you are asking about the Klein and Spring Independetn School Districts. Spring is an unincorporated area of Harris County, Klein is not. You can check the Texas Education Agency for the boundary maps for the various school districts.
