Why is sororum a genitive plural? Is it possibly a typo for sororem? However I have checked several different online texts of De Bello Gallico and they all have the same thing.
ipsum ex Helvetiis uxorem habere, sororum ex matre et propinquas suas nuptum in alias civitates conlocasse.
De Bello Gallico, 1.17.7
