It seems that a number of street names in this area are unclear as to origin. Probably they were named after the wives or children of the developers. Charles St as we as St. Nicholas Ave were all called Ann St at one time. So it seems that "Ann" whomever she was, had powerful friends in City Hall. Though not powerful enough to have prevented her name from falling into oblivion.
