IMHO, I really don’t see any resemblence between Barry and Stan Dunham, and between Barry and Ann Dunham in their facial features or body types. Ann Dunham was very heavy in her later years and also heavy in high school. Barry is a strapping lad such as Barney Fife.
Really? I thought they looked quite similar, and it has been remarked by a lot of other people (What was his aunt's name that lives in Arkansas?) that he very closely resembled Stanley Armour Dunham. I actually thought the resemblance was somewhat uncanny.
