Winter, C. (1950). Beiträge zur Namenforschung, Volumes 1-3. the University of California. p. 170. OCLC636671800. "The name Γίδος, of Andronicos I Gidos Comnenos of Trapezous (around 1200) and of Alexios Gidos (the father of the first) is traced by N. Bees* back to mod. Gr. γίδα f., γίδι n. goat. Be it noted here that from mod. Gr. Γίδα a name form Γίδας ought to be expected, cf. Κατσίκας from κατσίκα, and from mod. Gr. γίδι the personal name Γίδης as κριάρι – Κριάρης; περιστέρι – Περιστέρης etc. ;"
