I am also a descendant of the Higbee clan going back to William I, Prince of Orange. My mother gave us a copy of the 'Higbee Geneology' printed in 1910, updated in 1970. It documents a Tyler Higbee, son of James Jr and Mary Fenton from Orange Co., N.Y.. It references multiple Williams but no William Tyler. Feel free to email me if you haven't found your answers.
