In "Shifting Scenes - Carter County Montana" Vol. I page 364, there is a write-up on Charles Eugene Hubbard who was born at Exira, Iowa in 1867 and another write-up on James Edgar Hubbard who was also born at Exira, Iowa. I believe they were brothers. Could either of these be related to you? I can send you the write-ups if you like. Contact me at mahlersl@pacbell.net
