(AP) — Up to 30 landowners in southwest Nebraska’s Red Willow County may have deeds that contain inaccurate descriptions that have persisted for more than 90 years.

County commissioners learned Monday that the errors may stem from a 1921 map on which roads, fences and crop lines were not situated on quarter-section and section lines in the northwest corner of the county. Subsequent land buyers measured their land off the roads, giving rise to more inconsistencies.

A 1962 map retraced the 1921 map, so the errors weren’t corrected.

Seven or eight years ago, County Commissioner Vesta Dack and her husband, Dean, bought some pasture and discovered the problem. They paid for surveys and had corrections made to their deed.
