From the Webster dictionary: AUGHT means anything and zero. It is also a NAUGHT (as in nothing) misdivided as an AUGHT.
The anything goes AUGHT (which is not a "nothing") combined with the strong and long lived TREE is the perfect definition for an AUGHTREE (AUTREY).
Since other Autreys use the 0 + tree symbol as a signature, (E.A. and Hercules to name two) I have chosen to personalize the family icon with my "lea" (Lucy Ellen Autrey) initials combined, when a digital signature is appropriate, with a Yellow-faced independent bee.
