I just so happen to come across this very old posting while I was looking into my grandmothers history. She was Bessie Brooks Odell. Married to John Odell who is a son of the William W. Odell you were searching for. I recognize some of the sibling names such as as Chester Odell. I met him when I was about 12. Oh and I remember meeting my grandfather's (John Odell) mother. I wonder if that was Sarah Bowers. This would have been in the mid 70s and I remember taking a trip to Colorado to see her. Also there was family near Carlsbad Caverns.
