My research has Benjamin coming to Ohio from England about 1800. About 1840-1850, The Family migrated to Southern Iowa, and appears to be many records in Appanoose Co. Iowa. Three of his Grandson's, John Benjamin, Moses Austin, and Noah Lewis moved to and died in Nuckolls County, Nebraska. Another Grandson settled and died in Decatur County, Kansas. Two other grandsons remained in the Appanoose Co., Iowa. I have no records of this family being in Nemaha County, Nebraska ,but welcome any information on those Adamson's also. Jerry F.
