The subject of a question can go either at the end or the beginning of a question, before or after the verb. That being said, most people teach that the subject follows the verb in a question, but I've heard that rule broken hundreds of times.
If the subject is a pronoun, like usted, it can be omitted entirely once established.
In the constructions you posted that contain dónde or cuándo, the up-front placement of the subject pronoun seems to be an attention grabber, but is grammatically the same as placing the subject pronoun after the verb. This seems to be a more popular placement, however.
I believe these sentences are all equivalent:
¿Dónde nació? (if the subject is understood)
¿Dónde nació usted?
¿Usted dónde nació?
(y) usted, ¿dónde nació?
¿Dónde usted nació?
