Wilber Nebraska is the county seat of Saline County. They would have wills or estate papers at the Probate Court. Birth records were not kept until 1910 and deaths sporadically in 1904. Obituaries were in the Dorchester Star newspaper, and copies can be obtained from the Nebraska State Historical Socieity at 15th & R in Lincoln Nebraska. I believe the cost is $5.00 for the Historical Society and Wilbur charges 50 cents for marriages and $5.00 for wills and estates. These places are fantastic and of great help. donna
