Unfortunately the Idaho Statesman's website is currently under construction, so I could not access the obitaury you referred to Mr. Spaeth.
However, I did locate an obituary for William I. Spaeth.In case this might be of interst to anyone else, this is the basics of what was reported in the North Side News (the newspaper for Jerome, Idaho) in the Obituary for William I. Spaeth:
FORMER MAYOR DIES AT BOISE HOSPITAL MARCH 9 (1973)
Funeral services for William I. Spaeth 76, a former mayor, city councilman and businessman at Jerome were held March 12 at 2:30 p.m. at First Presbyterian church.......
He was born Sept. 3, 1896 at St. Louis, MO., and died March 9, 1973, in a Boise hospital........
After moving in 1930 to Jerome, where he was an automobile dealer until his retirement in 1962, Mr. Spaeth served for six years on the Jerome City Council, was council chairman, and also served a term as mayor of Jerome.
He served in France with the U.S. Armed Forces during World War I.He later moved to Idaho where he graduated from Link's School of Business in Boise.
He married the former Helen Greer June 9, 1920.She died in 1964.
He was an automobile dealer at Notus from 1920 to 1930 prior to moving to Jerome............
Surviving are a daughter, Mrs. Reed (Barbara) Clements, Lewiston (Idaho); a son, William J. Spaeth, Boise.
Two sisters, Mrs. Amelia McPherson, Caldwell (Idaho), and Mrs. Helen Norris, Big Fork, Mont.; two brothers, Robert G. Spaeth, Coeur D'Alene (Idaho), and Charles Spaeth, Yakima, Wash.; and five grandchildren.
I also found a man named William Spaeth, who was single, and 30 years old, and his POB was listed as Prussia, on the 1880 census of St. Louis. I'm wondering if this may have been William I. and Annie D. Spaeth's father (and the father of Charles, Robert G., Helen and Amelia as well). Does this information ring any bells for anyone here? Thanks
