There was a Bayhead Post Office near present-day Cottonwood, Houston County, Alabama, and one in Bay County, Florida. You can get to a map at the USGS website: http://mapping.usgs.gov/www/gnis/gnisform.html Fill in 2 blanks: Feature Name is Bayhead, State is Alabama or Florida, and submit. It will take you to a page with a link to a map!! Happy Hunting! Scott
