The site contains a wide variety of information about Hemingways, describes the progress with the Hemingway DNA Project and details of the Gatherings that are planned or have been held. There is a guestbook where you can leave information or comments for others about your own research.
I know many people get quite upset if their name gets spelt wrongly. The thing is, this is how most of the current variants have come about. My own father's birth certificate has two spellings on the one certificate for instance (Hemingway & Hemmingway).
Over the years I have come across 117 spelling variations or close variants - some I think you would agree are just simple spelling errors that have been promulgated and some are more likely longer term mutations. See Hemingway Variants below.
