Abbott 1898 An envelope postmarked Abbott, an earlier name for Zephyrhills, in 1898. The first postmaster was Amanda Spangler Isaacs. She probably named the post office for her first husband John W. Abbott (1820-1849) or for her son Dr. Joseph M. Abbott (1844-1906). The post office name was changed to Zephyrhills in 1910. This item was provided by Jack Malarkey.
