I checked with a francophone colleague of mine and he confirmed that st is the short form of saint (masculine) and ste is the short form of sainte (feminine form of saint) so a female saint in French is a Sainte (Ste. Anne, Ste. Marie, Ste. Judy). He did check in a french grammar book ,and it indicated that for place names from religious figures it should not be abbreviated, instead the whole Sainte or Saint should be used.
