Seguin
Seguin or Séguín is a French and Gascon name. It may be a Frankish name, from Germanic origin (sig-, that is, "victory", cf. modern German sieg, and -win, that is, "friend", related to modern English "win"). Seghin, Sigiwinus, Siguvinus, Siguinus, Siguin, Sigiwin, Sigwin, Sigoin and Segouin are alternate variants. According to Jean de Jaurgain quoting primary source Saint Andrew of Bordeaux, the original Vascon name written in Latin was Sihiminum, related to Basque Seme(no), meaning 'son' (cf. ancient Aquitanian Basque "seni" meaning 'boy' > modern "sehi"). It is also spelled Scimin, Skimin, Scemenus, Semen, Semeno, Xemen, or Ximen and gave rise to the Castilian Ximeno and Jimeno. Both Semen and Seguin, unrelated names, are found in sources.
