I have quite a bit of research posted on my website: www.tuckerfamilytree.info
with a chapter on Craveners who all pretty much can trace roots back to the original George Cravener family of Alleghany Co, Pa. The site is free and hopefully of help to researchers of the Cravener name in the US. I am fairly certain all Craveners in the US can trace back to George. My mother's maiden name is Cravener.
