"AMOS ANDERSON" AND NEBRASKA
WALLACE H. ANDERSON, county attorney of Allen County, has won many of the honors of his profession during his active practice at Iola, is a native of Kansas, and is a worthy product of Kansas country life and schools.
His family came to Brown County in 1869 and Wallace Harmon Anderson was born on the farm there December 26, 1877. His ancestors were Englishmen who came to Pennsylvania in colonial days. His grandfather Amos Anderson was born in Pennsylvania in 1802, and had a brother who served in the War of 1812. AMOS ANDERSON lived in Ohio, in Iowa, came to Kansas about 1871, but finally retired from his work as a farmer and moved to Nebraska. His death occurred at Ashland in that state in 1891. He married Miss Blazer, who was born in Pennsylvania and died in Nebraska. She'was of Pennsylvania German stock, and one of her ancestors, perhaps an uncle, was a member of the historic Boston Ten Party.
AMOS J. ANDERSON, father of the Allen County attorney, was born in Ohio December 17, 1844, but in early childhood his parents removed to Henry County, Iowa, and he grew up in the country near Mount Pleasant. He was still a youth when he enlisted in 1862 for service in the Union army He spent three years three months in Company E of the Ninth Iowa Cavalry, and fought until the close of hostilities. His principal service was up and down the Mississippi River and in the State of Arkansas, and he waged many fights against the guerrillas and border ruffians of the period. He was also with the Federal armies that pushed back Price's raid through Missouri and Kansas
