The photographer is Elmer Carlson Morris ILL.
Ernest Gerhard Tweet 15 years old
From that information he must have been born in 1896 or thereabouts.
Thanks for stopping by.
I had time too look a bit. At Find A Grave:
Ernest Gerhard Tweet Born Dec 9 1895 Illinois Died May 7 1917 in Iowa. He is buried in Lost Island Lutheran Cemetery. His parents were Henry Tweet 1862 –1931 and Anna Holland Tweet 1865-1944.
Ernest had one sister Agnes P. Tweet Gould 1898-1987
I wonder why he died so young?
