Many of the schools around Ellendale have been losing a lot of enrollment, as the country-side has been depoplulated (farm consolidation). Check with the school districts around the area. In addition to Oakes, check out LaMoure, Edgley-Kulm, and Ashley for both employment within the school districts and for churches. Call a Pastor of a church of interest and explain your situation. Housing in any of those towns should be very inexpensive.
