Dr. Oscar W Matthews, Iowa, d between 1912 and 1930
I am looking for information on the death of my great uncle, Dr. Oscar W(illiam?) Matthews, a physician in Des Moines, IA.I know he was alive in 1912, as he is listed in a city directory; I know he was dead by 1930, as his wife shows up in the 1930 US Census living with her daughter, and listed as a widow.I have not been able to find any trace in the 1920 US Census.
I would appreciate any information.
