Aha, that probably was the right Donald I found - as the son of Louis Frazier is described in the following bio as "an electrician and builder of federal airways and landing fields, and is a construction engineer."
A Biography from the Nebraskana Society
Louis Wood Frazier
A resident of Nebraska for the past 61 years, Louis Wood Frazier was born at Martins Ferry, Ohio, December 2, 1869, the son of Joseph and Talitha (Spence) Frazier. His father, who was a newspaper editor, was born at Mt. Pleasant, Ohio, June 11, 1826, and died at Fairmont, Nebraska, August 13, 1891. He served as lieutenant in Company G, 15th Ohio Volunteer Infantry during the Civil War; his ancestry was Scotch.
Talitha (Spence) Frazier, mother of Louis Frazier, was a homemaker and a talented artist. She was born in Harrison County, Ohio, December 1, 1837, of Irish parentage, and died at Fairmont, Nebraska, January 28, 1903.
Mr. Frazier has been editor and publisher of the Fillmore Chronicle since July 1, 1885, and has been active in civic affairs at Fairmont during that period. He is a member of the Nebraska State Historical Society, the Nebraskana Society, and the district, state, and national press associations. A charter member of the Fairmont Commercial Club, he has always been interested in the progress of his community. He is a Scottish Rite Mason, and Shriner.
An independent Republican, Mr. Frazier served as state printer of Nebraska from 1903 to 1909, and was postmaster at Fairmont, from 1909 to 1913. He married Anna Shoff at Grafton, Nebraska, April 7, 1902. Mrs. Frazier, who is a newspaper reporter, was born of German and English parentage at Mt. Pleasant, Iowa, November 30, 1867. Their son, Donald, who was born July 20, 1903, married Ethel Brown. He is an electrician and builder of federal airways and landing fields, and is a construction engineer. Residence: Fairmont.
BTW on the same census page with Ethel and boys, Louis and Anna, is another Frazier family:
William Volentine & Fannie Belle (Bivens) Frazier, daughter Mildred b 1908 and apparently this family had a son Ira Lewis Frazier. See the 1940 census, free (for the moment) and searchable at Ancestry.com. William's name is transcribed as "Frezie" but a little sleuthing suggests it is Frazier (as indeed it looked to me when I first read the original handwritten document). This William Frazier is born about 1868 in Missouri. Family Search usually has its own transcription which may read "Frazier." I don't see a connection to your Fraziers - perhaps you will.
