This site is intended to be a source for:
- Personal histories.
- Action history.
- Any other related information.

This work is a collaboration between Paul Wallace and Mark Boyd, grandsons of Sgt. Roy Bailey and Pvt. A.D. Boyd.
If you have any information to add, or questions to ask, please e-mail mark@markboyd.info-

Paul has put together a CD that combines Roy Bailey's diary, A.D. Boyd's letters and commentary from Ohio In the Rainbow as well as other comments. You can download the CD image here in .zip format.

We also have available several books and newspaper articles that we are using as reference. The primary written history of the 166th in WW1 is Ohio In The Rainbow by Robert Cheseldine.
