The story 'Names/Nombres' has themes of belonging and not belonging. Julia Alvarez feels a bit out of place in the US at first because of her name. But as she matures, she starts to find a sense of belonging within her own cultural identity. Also, the theme of heritage is important. Her name is linked to her Dominican heritage, and the story shows how she comes to value that heritage more over time.
Identity is likely a main theme. As mentioned before, names are tied to identity, and the story with its focus on names in two languages might be exploring how characters' identities are shaped by their names and the cultures associated with them.
