presidential heritage

[storm]

Forgive my ignorance of american presidents but I was wondering how many of them could claim to be of british descent, there does seem to be a lot of anglo saxon names involved, Bush, Nixon, Carter, Wilson, Ford, Lincoln etc. Has there ever been a greek american as president or italian, spanish and so on.
Over here in England we always hear about old country identities in the U.S. but I've never heard any reference to british or english heritage, is this because people are ashamed of it or is there some other reason.
