Meaning & History
In the case of a male bearer, this name is probably (but not certain) a short form of a Germanic name containing the Old High Germanic element sigu "victory" (a younger form of Gothic sigis, see Sigisbert). It has also been spotted as a short name for Silvester. In the case of a female bearer, this name is most often seen as a short form for Cecilia.
