What do you need their name for? Do you need their legal name? As in, actually legally need it? Realise that you'll probably need several name fields in different places depending on what you're doing, i.e. an e-commerce app may have a name to address someone by, a name on a billing address, a name on a shipping address, a name on a payment method... all of which can vary for the same person. If all you need is a way to address them, just a single name field.
